I am doing an electronics project that involves transmitting and receiving information on the 915MHz ISM band. I need to make the enclosure as small as possible. However, that means that I don't have a lot of space for my antenna that is tuned for the 915MHz ISM band.
Hwow will the performance be affected by the fact that I am folding the antenna like this? Am I better off just using a helical antenna in this case?
