Abstract
A lens integrated beamsteering antenna array with improved scan coverage is disclosed. The lens integrated beamsteering antenna array comprises a dielectric lens having a front surface and a back surface and an antenna array embedded within the dielectric lens proximate to the back surface of the dielectric lens. The antenna array is directed towards the front surface of the dielectric lens and is configured to transmit and receive through the dielectric lens and the front surface.

A lens integrated beamsteering antenna array with improved scan coverage, the lens integrated beamsteering antenna array comprising:
- a dielectric lens having a front surface and a back surface;
- and
- an antenna array embedded within the dielectric lens proximate to the back surface of the dielectric lens,
- wherein
- the antenna array is directed towards the front surface of the dielectric lens and is configured to transmit and receive through the dielectric lens and the front surface at a first frequency, and
- the dielectric lens has a thickness that is configured to allow the antenna array to form an antenna beam within the dielectric lens at the first frequency.
A method for extending a scan coverage of an antenna array integrated within a dielectric lens having a front surface and back surface, wherein the dielectric lens is embedded within the dielectric lens proximate to the back surface, the method comprising:
- producing an antenna beam, with the antenna array, within the dielectric lens that is directed towards a front surface of the dielectric lens;
- and
- deflecting the antenna beam away from an antenna boresight of the antenna array when the antenna beam emerges from the dielectric lens at the front surface.
