Validation of a broadband E-shaped antenna in a real semi-urban passive radar scenario

In this paper, a patch antenna designed to operate in a UHF passive radar with a broadband about 19% is validated in a real semi-urban scenario. Novel techniques, such as using air gap as substrate and E shaped patch, were considered in the fabrication. The proposed solution is used in the surveillance acquisition system of IDEPAR demonstrator, a DVB-T based passive radar system, to evaluate the detection performance with real radar data acquired in a terrestrial scenario.
