Summary:
A Fabry-Perot cavity antenna with extended 3dB gain bandwidth is presented in this paper. The proposed structure consists of a rectangular-patch microstrip antenna, on top of which a planar partial reflective surface (PRS) is mounted. Two periodic planar structures, i.e. metasurfaces, with different unit cells are printed on both sides of a 1.5mm-thick Rogers 5880 substrate, forming a novel PRS. It is then confirmed by simulation and experimental results that the proposed antenna operates at around 12GHz with a relative bandwidth of 19.77%. The measured gain can reach 16dB with a 3dB gain bandwidth of 11.23%, much more than a Fabry-Perot Cavity antenna with a traditional PRS.
