Abstract :
An in-depth investigation of a multi-mode reconfigurable aperture controlled by pin diode switches is presented. A method for reducing the coupling across the pin diode switches is explored, yielding a noticeable improvement in the isolation characteristics between ports. Strategic feeding of the patch antenna ports results in significantly improved radiation patterns, making the system suitable for multi-modal multi-functional phased array operations.
