A Wideband Dual Circularly-Polarized Metal Cavity Antenna Array
A novel wideband dual circularly polarised metal cavity antenna array is proposed. The radiating element consists of a tilted slot on the narrow wall of the ridged waveguide and a bending slot at the bottom of the L-shaped wall. RHCP and LHCP antenna arrays have the same waveguide structure and the difference is in the orientation of the slots. The impedance bandwidth of the antenna at the operating frequency is about 15% (9.0GHz~10.5GHz), and the axial ratio bandwidth is about 20% (8.8GHz~10.8GHz). The antenna has the characteristics of high efficiency, simple structure and wide band.
