High Gain Patch Antenna Using a Frequency Selective Surface (FSS)
A novel design of a New Frequency Selective Surface (NFSS) is presented, characterized and employed for the gain enhancement of a microstrip antenna operating at 5.2GHz. The new FSS structure is then applied as a superstrate to a conventional microstrip patch antenna. This paper is to study low profile with compact size superstrate. Simulation and analysis results of the FSS design with CST Microwave studio are compared with results from the equivalent circuit of proposed FSS unit cell in ADS software to improve characteristics in terms of transmission and reflection responses.
