Broad band printed MM-wave antenna with reflector element

Following the demands of modern society for more mobility and more information, future generation base stations have to provide more data transmission capacity requiring a flexible management of the resources code, time, bandwidth and space. In this contribution, a class of broadband printed mm-wave antennas based on a low cost stacked patch (SP) is presented and can be incorporated into a variety of systems due to their large operating bandwidth. The enhanced B.W. of about 40% (for VSWR ≤ 2) is obtained by this proposed antenna. Its performance with reduced back-radiation has also been investigated.
