Lens based antenna for super high capacity wireless communications systems
First Claim
1. An antenna for use in wireless communications, comprising:
- a first sub-antenna, comprising a first cylindrical lens and a first emitter that is coupled to the first cylindrical lens, wherein the first cylindrical lens and the first emitter are arranged to provide a first field of view at a first wavelength;
a second sub-antenna, comprising a second cylindrical lens and a second emitter that is coupled to the second cylindrical lens, wherein the second cylindrical lens and the second emitter are arranged to provide a second field of view at a second wavelength; and
a cable that is communicatively coupled to the first and second emitters by traversing a first gap between the first and second cylindrical lenses,wherein the first and second field of views are non-overlapping,wherein the first and second sub-antennae are arranged vertically along their respective central axes.

Abstract
An antenna includes a stack of cylindrical lenses combined with feed elements to provide multi-beam coverage for a given wireless communication sector. Each cylindrical lens disc has approximately the same height as the feed elements being used with the lens. To overcome the problem of interference from cables and opposing feeds, feed elements are placed around the lens. The cylindrical lenses are stacked such that a small gap exists between each pair of adjacent cylindrical lenses, allowing for cable lines to pass through between the pair of the cylindrical lenses, and thus removing interference for 360 degree coverage. Cable lines are arranged such that they only traverse the portion of the circumferential surfaces of the cylindrical lenses that do not interfere with the field of view of the RF signals generated by the corresponding feed elements.
