Abstract

Two antenna structures loaded with S-shape loaded reactive impedance surface (S-RIS) square and equilateral triangular shapes are designed and studied. The square Microstrip patch antenna is found to be resonant at two frequencies 4.8 and 6.8GHz in C-band. In the case of S-RIS loaded triangle it is resonant with high bandwidth in the frequency range of 7- 9.2GHz covering C-band and X-band frequencies respectively. This structure showed resonance at 7.6 GHz. The directive gain for S-RIS square Microstrip patch antenna is 5.9dBi at 4.8GHz whereas for S-RIS triangle Microstrip patch antenna the directive gain at 8.1GHz is 5.53dBi. It has been observed that both structures showed high gain at resonance frequencies. Square shape is resonant at two frequencies while triangular patch is resonant only one frequency with high bandwidth and gain. Both designs show miniaturization and high performance. Due to miniaturization and gain considerations proposed designs can be used to design and fabricate a phased array antenna for synthetic aperture radar (SAR) for dual band and high bandwidth applications. The simulation was performed in Computer Simulation Technology.
