Abstract
ABSTRACTIn this paper, a novel partially reflective metasurface (PRS) unit is proposed for beam deflection in a dual‐band shared aperture Fabry–Perot cavity antenna (DB‐FPA). It operates in the C‐band and X‐band. Independent control of different frequency bands can be achieved by adjusting the different parameters of the PRS unit. A coaxially fed patch antenna is used as the feed source for the proposed antenna. This antenna exhibits high aperture efficiency and can operate in two bands with a ratio of 1:1.67. The measurements indicate the impedance bandwidth dB of the DB‐FPA is 5.54‐6.48 GHz (15.6%) and 9.62–10.52 GHz (9%). The gain is 7.15 dBi at 6 GHz with an aperture efficiency of 34.8%, and 8.3 dBi at 10 GHz with an aperture efficiency of 14.5%. The beam deflection of at 6 GHz and at 10 GHz.
