Abstract
An antenna has a plurality of dielectric layers and a plurality of conducting layers. At least one of the dielectric layers comprises one or more regions with differing dielectric properties. A plurality of such antennas may be arranged in an antenna array. The array includes a radiating component etched in the array top first layer, a reflector embedded in a second layer below the top layer, a feeding network located in a third layer below the reflector, and a ground plane bottom layer configured to shield the feeding network in the bottom layer. At least one of the layers of the array is a non-uniform dielectric layer of a material having a substantially different electrical property compared to the array dielectric and conducting layers.

An antenna comprising:
- a plurality of dielectric layers, and a plurality of conducting layers, wherein at least one of said dielectric layers comprises one or more regions with differing dielectric properties.
An antenna array comprising a plurality of antennas arranged on a plurality of dielectric and conducting layers, said antenna array comprising:
- a radiating component etched in said array top first layer;
- a reflector embedded in a second layer below said top layer;
- a feeding network located in a third layer below said reflector;
- a ground plane bottom layer configured to shield said feeding network in said bottom layer, wherein at least one of said layers is a non-uniform dielectric layer, said non-uniform dielectric layer comprises a material having a substantially different electrical properties compared to said array dielectric and conducting layers.
