Abstract
This paper reveals the impact of the insertion of electromagnetic band gap (EBG) structures on the performance of circularly polarized (CP) patch-slot antenna with offset slot. An optimization is necessary to precise physical parameters in the aim to fix the resonance frequency at 3.2 GHz useful for weather radar, surface ship radar, and some communications satellites bands. The proposed antenna possesses lightweight, simplicity, low cost. The circular polarization is ensured by right-hand and left-hand circular polarization process (RHCP and LHCP) due to the two exciting sources.
Our investigation will confirm the simulation and experimental results of the EBG antenna involving new EBG structures.
