Abstract :
In this paper a high gain antenna array designed for High Power Microwaves applications (HPM) is presented. The antenna array is composed of four sub-arrays of four rectangular patch elements. These one are air based in order to limit losses and enhance radiating efficiency. The power is transmitted to each sub array through slot which is machined in a waveguide fed by a monopole antenna. A full set of measurements has been performed. The measured gain reaches 19 dBi and the efficiency is better than 80 %.
