Abstract: This paper describes the Ultra-Low Side Lobe Radiation of Concentric Circular Array Antenna, which employs evolutionary optimization techniques. Particle Swarm Optimization (PSO), which has ...

Abstract: A saddle-pattern dual circularly polarized (CP) dielectric resonator antenna (DRA) with a broad half-power beamwidth (HPBW) and axial ratio beamwidth (ARBW) is proposed in this letter. A ...
