Dual Band Horn Antenna Using Frequency Selective Surface Superstrate

Abstract

The demand for high gain, multi band and reconfigurable type compact antennas are required for modern communication systems. In this paper, a unit cell design using U-shape with sequential rotations is presented to obtain dual passband frequency response. The unit cell design shows dual passband characteristics for the frequency range of 8-9.96 GHz and 11.53-14 GHz. In the complete high gain antenna design, 3x5 frequency selective surface array with X-band Horn antenna is demonstrated. The proposed reconfigurable frequency design has produced dual band impedance matching and a high gain of 13.09dB at 9.5GHz and 13.12dB at 12GHz, respectively. Most suitable applications for proposed antenna include communication systems requiring frequency selective, multi band and high gain antennas.
