Abstract :
The design and experimental results of a C-band dual polarized aperture-coupled stacked patch microstrip antenna are presented. The antenna is capable of operating over a bandwidth of 26% with improved front-to-back ratio. The patches are excited through crossed slots. The feed lines are separated by a thin substrate to enhance the port decoupling. The measured impedance and the radiation pattern of the antenna at C-band are presented.
