Embodiment Construction

[0049] Antennas with multi-beam beamforming networks having driven planar arrays of radiating elements, such as Butler matrices, have been developed. However, multi-beam beamforming networks have several potential disadvantages, including asymmetrical beams and problems associated with port-to-port isolation, loss of gain, and / or narrow bandwidth. Multi-beam antennas have also been proposed using Luneburg lenses, which are multilayer lenses of generally spherical shape with dielectric materials having a different dielectric constant in each layer. Unfortunately, for many applications, Lemberg lenses are prohibitively expensive, and antenna systems using Lemberg lenses may still have problems with beamwidth stability over wide frequency bands.

[0050] US Patent Publication No. 2015 / 0091767 ("the '767 publication") proposes a multi-beam antenna with a linear array of radiating elements and a cylindrical RF lens formed from a composite dielectric material. RF lenses are used to...

Abstract

The present invention provides lens antennas that include a plurality of radiating elements and a lens positioned to receive electromagnetic radiation from at least one of the radiating elements, thelens comprising a composite dielectric material. The composite dielectric material comprises expandable gas-filled microspheres that are mixed with an inert binder, dielectric support materials such as foamed microspheres and particles of conductive material that are mixed together.

Description

[0001] Cross References to Related Applications [0002] The present application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application Serial No. 62 / 313,406, filed March 25, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to radio communications and, more particularly, to lenticular antennas for use in cellular and other communication systems. Background technique [0004] Cellular communication systems are well known in the art. In a cellular communication system, a geographical area is divided into a series of areas called "cells", and each cell is served by a base station. A base station may include one or more antennas configured to provide two-way radio frequency ("RF") communication with mobile subscribers geographically located within a cell served by the base station. In many cases, each base station serves multiple "sectors," and each of the multiple ant...
