This paper presents the design, fabrication, and characterization of a compact wideband antenna for high-power microwave applications. The antennas proposed are array of high-power wideband patches with high compactness and less than λ/10 thick. The concept developed can be fed by highvoltage signals (up to 60 kV) in repetitive operation. Two designs are produced at central frequencies of 350 MHz and 1 GHz. Their relative bandwidth is larger than 40% at 350 MHz and 25% at 1 GHz for S11 < −10 dB, respectively. The arrays studied produce a gain of more than 14 dB.Index Terms-Broad-band antennas, high-power microwave (HPM) antennas, patch antennas.
