Recent and future research trends in planar multi-beam antennas in the millimeter wave range at IETR-France

摘要

A review of some flat multi-beam antennas developed at IETR during the last 5 years (2010-2015) is reported. These antennas are based on quasi-optical and circuit-based beam forming networks (BFNs). The enhanced scanning capabilities of the proposed solutions will be shown. In addition, some antennas integrate antenna functions like monopulse techniques to enhance the angular resolution for tracking applications. The main concepts and features of the developed antennas will be reported. These antennas operate in different frequency band in the millimeter wave range and are realized with different fabrication processes.
