Hi, a friend asked that how to realize this kind of compact circularly polarized antenna.
the size is 60*60*5mm,
the frequency is 401 MHz,
bandwidth is 4MHz with VSWR<1.5, AR<3dB.
the direction is not very important
I think the size is the problem to realize.
could any one tell me how to realize this compact CP antenna, thank you very much.
