Abstract :
The design of a X-band single radiator for a wide-band dual polarized-aperture coupled stacked patch microstrip antenna is introduced. A bandwidth of 2 GHz with enhanced port decoupling, improved front to back ratio and high gain can be obtained by using thin substrates for the feeding network. Simulated and measured results of S-parameters and measured radiation patterns are presented
