Abstract
Aperture-coupled ESPAR antenna with a unique feed structure for switched beam application has been presented. The feed structure provides control over surface current of the driven element with the help of which main lobe can be steered in desired direction. This control has been achieved through the use of PIN-diodes. Finite element method has been utilized for design and simulated and measured results have been presented for validation. The antenna has the ability to steer the main beam in six directions. All radiation patterns are symmetric. The planar aperture-coupled nature of proposed antenna is ideal for integration and commercialization.
