Abstract :
The novel structure of a unique circularly polarized broadband antenna that combines an L-shaped probe with a partially covered circular slot has been presented. A principle that can be used to generate CP using the proposed structure has been presented using an L-shaped probe and a modified circular wide slot. Using the above, a 3 -dB AR bandwidth of 58% and matching bandwidth of 57% were obtained at 3.2 GHz.
