Antenna Design for Electronic Warfare Applications

In this paper, two antennas designed at the XLIM Research Institute are presented for high-power and high steering angle applications, especially in an electronic warfare context. The first antenna, inspired by a Koshelev antenna and powered by a Marx generator, can radiate a peak electric field of 1 MV/m at a distance of 1 m and with a duration of 1 ns. The second antenna based on the agile radiating matrix technology allows a ±60° steering angle from 1.2 GHz to 1.6 GHz while keeping low side-lobes levels.
