Multi-array antenna
First Claim
1. An antenna system, comprising:
- at least two linear antenna arrays comprising;
a first linear antenna array comprising a first plurality of antenna elements; and
a second linear antenna array comprising a second plurality of antenna elements, wherein the first linear antenna array is for transmitting and receiving signals in a first spectrum band, and wherein the second linear antenna array is for transmitting and receiving signals in a second spectrum band that is different from the first spectrum band;
wherein the first linear antenna array and second linear antenna array are arranged to form a combined linear array of antenna elements, wherein a length of the combined linear array of antenna elements is greater than a length of the first linear antenna array and a length of the second linear antenna array; and
wherein at least two consecutive antenna elements are common for both the first plurality of antenna elements and the second plurality of antenna elements, wherein the at least two consecutive antenna elements are deployed in a region of overlap between the length of the first linear antenna array and the length of the second linear antenna array, wherein the region of overlap includes the at least two consecutive antenna elements and does not include antenna elements of the first plurality of antenna elements that are exclusive to the first linear antenna array and does not include antenna elements of the second plurality of antenna elements that are exclusive to the second linear antenna array, wherein the at least two consecutive antenna elements operate contiguously across a range of frequencies between and including the first spectrum band and the second spectrum band.

Abstract
In one example, the present disclosure describes an antenna system with at least two linear antenna arrays, each having a plurality of antenna elements. Each array is designed to transmit and receive signals from different respective spectrum bands. The first antenna array and second antenna array are arranged to form one longer, combined linear array of antenna elements. In addition, at least one antenna element is shared between the first and second antenna arrays. In one example, the first antenna array is connected to a first RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the first antenna array and the second antenna array is connected to a second RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the second antenna array.
