Stacked microstrip antenna for wireless communication

DETAILED DESCRIPTION I 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.
2.
The antenna of claim 1, further comprising at least one additional antenna layer comprising an additional dielectric layer, an additional radiating layer disposed on said additional dielectric layer, and an additional short-circuiting means disposed on a selected side of said additional dielectric layer, wherein each of said additional antenna layers is stacked upon said microstrip antenna and each said additional short-circuiting means is substantially oriented 90 degrees apart from said short-circuiting means of a dielectric layer located directly below it.
3.
The antenna of claim 1, wherein said first and second dielectric layers and said first and second radiating layers are of substantially equal size.
4.
The antenna of claim 3, wherein said ground plate is of substantially equal size as said first dielectric layer.
5.
The antenna of claim 1, wherein each said dielectric layer has substantially equal dimensions on each side.
6.
The antenna of claim 1, wherein said first short-circuiting means covers substantially all of said first selected side of said first dielectric layer.
7.
The antenna of claim 6, wherein said second short-circuiting means covers substantially all of said second selected side of said second dielectric layer
