I am planning on making a board which will have some 2.4GHz RF capabilities, and would like to know if there is a cheap way to tune an IFA cheaply.
If I had access to the right equipment I could easily tune the antenna, but at the moment a multi-thousand dollar VNA is a pipe dream.
Is there anything that can be made or used on the cheap to get a crude antenna tuning going for this board?
Also something I saw which was interesting, on the antenna design specification it claims that no external matching components are needed. I'm assuming it would still be desired to have a pi network to deal with detunings caused by anything else on the board or in the environment right?
