چکیده :
Abstract— In this paper, we present a design for improving the bandwidth of Fabry-Perot cavity antenna (FPCA) employing a single layer partially reflective surface (PRS). A novel two-sided unit cell is suggested for PRS which is composed of a square patch and an H-shaped ring to create a positive reflection phase gradient. The designed antenna works in the X-band and for its feeding source, an aperture-coupled microstrip antenna is utilized. The single layer of PRS enables the advantage of a low profile along with its wide bandwidth. According to the simulation results, a 3dB gain bandwidth of 34.24% is obtained for the antenna in the frequency range of 8.21-11.6 GHz and an impedance bandwidth (S11<-10dB) of 50.17% in the frequency range of 8.72 -14.56 GHz.
