PCB antenna: The whitepaper "Quarterwave printed monopole antenna for 2.4GHz" explains how to design a PCB antenna.

The reference circuitry page link appears still to be broken.

Please, can you fix this link? Now I see 404:

Regarding the 50ohm impedance on transmission line: I downloaded the nRF52840-QIAA Reference Layout 1_0 and opened some of the files in Altium and took a look at the PCB stackup, thickness, track-width and track-separation to coplanar ground, on the part that goes to the (SMA?) connector.

I used two free impedance calculators and had them set to conductor-backed coplanar waveguide. With H=1.51mm, W=0.76mm, S=0.263mm and FR4 (er=4.5), I get for both calculators, Impedance of around 62ohm.

I get that these calculators are based on theoretical equations, but are they in fact approximately 24% off, when calculating the impedance? I guess you have actually measured the impedance to be 50ohm. What are your thoughts on the matter? And what do you recommend if I have different PCB thickness or stackup? What tool to use for approximate design? (I don't have ADS, CST etc.)

Hello Kristin, thanks for this tutorial, I am studying the Solar Powered Sensor Beacon example because this is very aproximated to my interest. I no have previous experience designing RF applications, but I am reading a lot about this interisting field, can I use this example as base to build a functional test? How is the antenna performance? Once more time, thank you for your knowledge!

Thanks for letting me know, I have updated the link to the reference circuitry page.
