Abstract :
A simple technique to develop a monopulse antenna has been presented. A dual feed dual linearly polarized aperture coupled antenna at L band has been developed as the basic part of the overall antenna. Two 4×2 arrays of aperture coupled square resonant patch antenna have been designed, fabricated and tested. The basic antenna parameters are optimized using (MoM) based commercial simulation software IE3D. A planar comparator has also been simulated and optimized using IE3D. The two antenna outputs are suitably combined through the comparator to get the sum and difference pattern necessary for direction finding. Measured results are also presented.
