Abstract
A technique for performance enhancement of a ribcage dipole antenna using a Frequency Selective Surface (FSS) based corner reflector in the C band (4-6 GHz) has been demonstrated in this paper. The proposed corner reflector is composed of two reflective FSS screens at an angle of 90° and is placed at a specific distance from the antenna. The reflector improves impedance bandwidth of the antenna from 27% to 53%. An improvement of 7-9dB is achieved in antenna gain over the frequency range of interest and it is maintained near 11 dBi with a variation of ±1dB in the C band. The proposed design offers a significant antenna front to back ratio of upto 28 dB.
