Title:
COMPACT TYPE MULTI-BEAM ANTENNA ARRAY WITH HIGH AND LOW FREQUENCY FILTER ELEMENTS ARRANGED IN INTERWOVEN MANNER
Document Type and Number:
WIPO Patent Application WO/2018/076491
Kind Code:
A1
Abstract:
Disclosed is a compact type multi-beam antenna array with high and low frequency filter elements arranged in an interwoven manner, comprising a first sub-array working on a first frequency band and a second sub-array working on a second frequency band which are provided on a substrate. The first sub-array and the second sub-array are arranged in an interwoven manner, wherein array elements of one sub-array are distributed dispersedly in spaces between array elements of the other sub-array. The first sub-array is formed by at least one first filter antenna unit without extra loss circuits. The second sub-array is formed by at least one second filter antenna unit without extra loss circuits. The entire array is arrayed and arranged in an interwoven manner by array elements of two frequency bands, which can reduce the size compared with the design of high frequency array elements and low frequency array elements being arrayed and arranged in a separated manner. Comparing with the design of array elements without a filter property being arrayed in an interwoven manner, the intercoupling effect between the array elements is smaller, which can maintain a good isolation performance.
