1. A wideband single antenna element comprising:
- a first conductive patch on a first plane;
a second conductive patch on a second plane, said second patch being spaced apart from said first patch;
a third conductive patch on a third plane, said third patch being spaced apart from said second patch such that said second patch is between said first patch and said third patch;
wherein said first patch is spaced apart from a ground plane such that said first patch is between said ground plane and said second patch and where said first conductive patch on said first plane is spaced apart from said second conductive patch on said second plane at a first distance and where said second conductive patch on said second plane is spaced apart from said third conductive patch on said third plane at a second distance, the second distance being a larger spacing than said first distance; and
said antenna element receives a signal feed by way of a slot in said ground plane;
said first, second, and third planes are parallel to each other and to said ground plane.

Abstract
Systems, methods, and devices relating to an antenna element and to an antenna array. A three level antenna element provides wideband coverage as well as dual polarization. Each of the three levels is a substrate with a conductive patch with the bottom level being spaced apart from the ground plane. Each of the three levels is spaced apart from the other levels with the spacings being non-uniform. The antenna element may be slot coupled by way of a cross slot in the ground plane. The antenna element, when used in an antenna array, may be surrounded by a metallic fence to heighten isolation from other antenna elements.
