Abstract :
A novel wide band circularly polarized vertical patch antenna with microstrip to slot-line transition to supply dual feed with anti-phase is presented in this paper. The results show that the 3dB axial ratio bandwidth of the antenna is more than 28%, and the return loss bandwidth (<-10dB) is around 38%. The antenna gain is around 8dBi and very stable in the frequency band of our interest.
