Stacked microstrip antenna for wireless communication
First Claim
1. A stacked microstrip antenna comprising:
- a ground plate;
a first dielectric layer disposed on said ground plate;
a first radiating layer disposed on said dielectric layer;
a second dielectric layer disposed on said first radiating layer;
a second radiating layer disposed on said second dielectric layer;
a first short-circuiting means disposed along a first selected side of said first dielectric layer and being connected to said first radiating layer and said ground plate; and
a second short-circuiting means disposed along a second selected side of said second dielectric layer and being connected to said second radiating layer and said first radiating layer;
wherein said first and second selected sides are oriented substantially 90 degrees apart and substantially form a right angle.

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.
