pp: 1-5Design and Implementation of Aperture Coupled Microstrip IFF AntennaMahmoud Niroo Jazi, Zaker Hossein Firouzeh, Hamid Mirmohammad-Sadeghi, and Gholamreza Askari doi:10.2529/PIERS071007064619 Downloads: 2039 Abstract:Design and implementation procedure of a wideband aperture coupled microstrip antenna in L-band frequency is introduced. To improve radiation performance of the microstrip antenna four structures are proposed. The structure with air substrate has the maximum frequency bandwidth. Experimental results of frequency bandwidth and radiation patterns of the optimum structure agree with the simulation results. The antenna has the gain of 8.5 dB, the frequency bandwidth of greater than 25%, and F/B better than 15 dB. This aperture coupled microstrip antenna can be used as an element of microstrip array antennas in IFF systems.References:1. Garg., R., P. Bhartia, I. Bahl, and A.
