I'm working with a signal generator testing module and there are two antennas on it. One of them is for generating 400 MHz and another is 900 MHz (these are estimates).
Right now I'm stuck on how I can change the antenna/device so that I can produce different frequencies.
The 5th picture should show how the antennas look. I would like to make an antenna similar to that one.
Is there a way for me to change one of the antennas if I wanted to put a higher frequency?
or make a new antenna that can generate specific frequency?
