Abstract :
The characteristics of a wideband and high gain slot antenna are investigated in terms of the reflection coefficients, radiation patterns, and gain. The slot antenna structure includes baffles, reflectors, and thick ground plane. Baffles and reflectors are used to increase antenna gain, thus reducing the coupling among slots on a thick ground plane. This antenna structure has obtained more wideband characteristics than a conventional aperture coupled antenna and its improved antenna gain therefore reduces side lobes and back lobe.
