ABSTRACT:
A stacked short-circuited microstrip antenna including a ground plate attached to a bottom layer, where each layer of the antenna is a dielectric layer with a radiating plate affixed to its top and one side of each dielectric layer is short-circuited. The short-circuited side of each dielectric layer is positioned 90 degrees apart from the short-circuit directly below it in the stacked layers. The antenna configuration allows for a physically small microstrip antenna with a sufficiently large resonant band width for use with a cellular phone or other communication device and also benefits from circular polarization which reduces signal loss in bad weather or another sources of interference.
