I'm very impressed with the quality of the distortion.

This is completely amazing! I never thought that one day i would understand this.

Thanks, but You didn't mention the most important part - process of matching.

i am facing issue when i zoom the footprint in pcb the pin number goes smaller to smaller, Kindly guide me

Hi Phil/any other commenters, I was curious how often register level programming is used in industry?

I have a doubt.... How is power gonna flow at the beginning if no 5.1k resistor are connected to the CC pins?

I'm new to this EDA design. Where can I download the antenna footprint to add in the circuit design?

very nice Mr. Phil 🙂

thanks for sharing, adding or bringin up some GUI over HDMI or LCD would be highly appreciated

Thank you for your fantastic videos Phil. By far the best educational channel re PCB/circuit design on youtube. Also, looking forward to a video on designing PCB trace antennas for sub-GHz trancievers! please design a loop antenna for us!

Wow, someone turned the difficulty dial to 11.

Connecting NRST to a grounded capacitor initially made me think the reset was being wired low. That capacitor should charge from NRST (which has an internal pull-up resistor) until it reaches capacity and then stop, leaving NRST high. This is effectively a power-on reset with a delay. Mentioning this in case anyone else was alarmed by this.

Great example, I've been following your videos for some time. So far I've been able to set up and program my custom board to interact with an I2C sensor and send data through USB com port!

Amazing video as usual, also looked at your previous DSP videos to learn more about dsp algos and DMA, as I recently got an project related to DSP so started to get more involved into it. Keep uploading videos like these really help full.

Great video! Question: What options are available to minimize the time delay between the raw and filtered signal?

Hello Phil's Lab, could you recommend me a microcontroller that I could use to control the gates of the two keying bridges. It is important that it generates PWM signals with a sine structure. Moreover, the two sine functions created in this way must be mutually shifted by an angle of 90 degrees regardless of the frequency within 0 - 500 Hz. PWM carrier frequency not less than 15 kHz. Ultimately, the system is to power the gates of 8 IGBT switching transistors of my 6 kW new generation Brushless Hybrid Fast - Rotation Motor. Thank you in advance and best regards 👋😀💖.

I'm surprised to hear PCB Design is so rare in EE courses. My university was pretty heavy on it with the very first semester having the assignment of creating whatever we wanted on a self-etched board that goes on a magnetic wall (which had copper strips supplying 5V to the boards) and every project afterwards all had some aspect that required PCB design to realize or to even hope to function. At graduation that very first assignment would be activated once more and then returned as a parting gift. It now hangs on my Fridge! ^^ Guess i'm very lucky to have gotten an education that was given by a group that were engineers first, Professors second. These days i keep designing and having PCBs made constantly as i keep learning new things. There is something about your creations coming alive that never gets old. I've also started to teach myself Mechanical engineering so i can wield the prevalence of 3D-Printing and open some very exciting new doors. Currently migrating all my old work to KiCad. Was taught in Eagle during university, but with its limitations and imminent deprecation it would be unwise to start a major project with it.

Thanks for the great content! My headache of choosing a buck converter is gone :)

Thanks a lot for this course Phil! This helped me a lot to understand more about PCB design and of course, I now understand how to use KiCAD!

Thank you

what command should I use to run the install_drivers script ?

Will you switch to Zephyr on STM32 or will you continue using STMCube and STM32 HAL?

Thank for this detailed guide. But what will be the minimal tuning process for this antena once you receive a board? And what minimal set of equipment is necessary to tune it? For example, will nanoVNA be enough?

Thank you for your videos - you always seem to make one on just the topic I'm trying to figure out. You've made a few on antenna design and matching but have you considered making one on the later stage of testing and tuning a matching network- perhaps using an inexpensive VNA?

I can choose 360p or 1080p premium....

7 hours in, look at bar, 20 minutes remaining. oh well, i really to eat.

Where can l find the full tutorial for this PCB project

Another excellent video, thanks for your work.

Another excellent video. What is your process for tuning the matching network? I went through the process of trying to tune a somewhat similar design with an el cheapo vector network analyser and ultimately still had to iterate through nearby values. Ultimately got an acceptable result but didn't feel efficient. Thanks.

Would have been great if you showed some actual measurement data for this layout.

Thank you for great resources. I found it is not only tricky to design and implement any antenna (I just copy/paste from the reference design), but as well one needs some HAM equipment to validate the result (SWR ration, transmition spectrum, harmonics, ...)

It´s good practice to place the pads of the matching network inside the trace. Otherwise you have open stups when you don´t assemble some components. For example if you do not place the capacitor next to your antenna it doesn´t care, because you basically have the trace to the antenna and no open stub.

I've been waiting for years for a video like this, thankyou! One question: if the ceramic antenna doesn't work (in my case I'm getting brownouts on my custom ESP32 board when starting wifi) how would you debug what is wrong? The world of RF is very foreign to me and it's hard to find resources that clearly explain what is happening

Very good video as usual, Id be interested to see a follow up video on the tuning process

Can you point me to your Quadcopter series please ? Great vid !....cheers.

Thank you this is exactly what I needed right now

Thank you Phil for this insightful content and for all you did on your RUclips channel. I bought your course on Fedevel academy " Mixed-signal Hardware design with kicad", the content is relevent, and I highly recomend it to anyone who wants to learn many tricks and tips in Hardware design.

A helpful tip for newer folks: If you're feeding your antenna with a coplanar waveguide, pull back the solder mask from the ground copper directly adjacent to the feed line. It allows you to solder shunt passive components at any point along the line, which can help you swing the impedance around the Smith chart as you'd like. It's also helpful to know that, though chip antennas are usually "suspended" (NOT over a ground plane,) chip antennas use the adjacent ground plane of your PCB to radiate. Therefore, you DO (probably) need a ground plane if you use a chip antenna, except for the region with no ground. Efficiency ratings and gain for antennae are often determined by testing the antenna on a PCB with a massive ground plane. If your board is small, this can affect the radiation pattern and efficiency, and your performance won't match the datasheet specs. Awesome video as always.

Is the course done with Altium?

Thank you. Love your PCB design series :) keep up the awesome work.

How can I get in touch with you, am having some trouble with the PCB i want to design. A flight controller with some new add ins i can figure how to integrate

👍🙏❤️

Thank you sir! I've made my first couple boards because of your tutorials and they work! You're awesome so thanks for sharing all of this knowledge for free.

I'm blessed to have you as a guide for PCB designs. Love your videos😍

Perfect timing!

First year EE, you make such an incredible impact in making more advanced concepts so accessible and practical, and makes me so excited to take on bigger and bigger projects outside of class. Thank you!

*Summary* **General:** * *(**0:00**)* Chip antennas are small, self-contained antennas suitable for applications where space is limited. * *(**0:00**)* They offer flexibility in terms of frequency, gain, and bandwidth options. * *(**0:00**)* However, they are sensitive to placement, routing, and surrounding components, requiring careful PCB design and tuning. *Chip Antenna Selection:* * *(**4:43**)* Always consider pre-certified modules first for commercial products, as they simplify the certification process. * *(**5:58**)* Choose chip antennas based on your application's frequency (e.g., 2.4 GHz for Bluetooth), mounting type (e.g., center mount), size, gain, and impedance. * *(**7:53**)* Distributor websites and manufacturer datasheets provide crucial information for antenna selection. *Matching Network:* * *(**12:33**)* Impedance matching between the RF transceiver and the antenna is essential for optimal power transfer and RF performance. * *(**12:33**)* Matching networks typically consist of capacitors and inductors. * *(**18:44**)* While datasheets provide recommended values, tuning on the final PCB design is usually necessary. *PCB Design:* * *(**22:31**)* Always refer to the chip antenna manufacturer's datasheet for PCB layout recommendations. * *(**24:54**)* Keep trace lengths and component sizes small relative to the operating wavelength to minimize impedance control issues. * *(**29:24**)* Avoid ground planes directly underneath the chip antenna, as this can affect its performance. * *(**31:29**)* Use stitching vias around ground polygons near the antenna feed point to ensure a good ground connection. i used gemini 1.5 pro to summarize the transcript

This channel is OP, thank you 🙏🏽

Are you interested in creating a new course? including pcie, ddr4,sata, lvds design, both hardware and software. Based on an zynq ulscascale + for example 😊

Another excellent video! Thank you for representing good engineering practice.
