A Metasurface-Based Slot Coupled Circularly Polarized Antenna for Satellite Communication Application
In this letter, a novel frequency-independent circular polarized antenna is proposed for satellite communication application. It consists of a slot coupled antenna and a planar metasurface. Four compact sequential L-shaped feeding lines could generate energy to the metasurface through the metallic ground embedded cross slot. Therefore, surface waves could propagate on the metasurface, making the antenna generate additional resonances. Then, wide impedance bandwidth and axial ratio bandwidth of the proposed antenna can be achieved. Besides, the proposed antenna has low profile (0.05 λ0at 3.5 GHz), frequency independent, large front-to-back ratio, high gain, and wide half-power beamwidth property. It has great potential in global satellite communication systems and satellite navigation systems (S band and C band).
