摘要
A configuration for a narrow-band rugged high-power antenna with a horizontally polarized fan-beam radiation pattern is proposed. This antenna is a longitudinal aperture array in the narrow wall of an air-filled rectangular waveguide, and it produces intentional electromagnetic interference for military purposes. It is to be approximately vertically front mounted on a land vehicle operating in a war zone for neutralizing hot-wire detonators from a safe distance. Computational electromagnetic analysis is used for analyzing the individual array elements, and then standard microwave network analysis is used for the initial array design. Full-wave analysis is used to validate the resulting array design and an improved array design. Experimental data at 10 GHz is presented to further validate the full-wave analysis. A theoretical estimate for the power handling capability is presented for the final array design scaled to operate at a frequency in the industrial frequency band (902-928 MHz).
