Abstract

Abstract

In conventional High Power Microwave(HPM) waveguide arrays of longitudinal shunt slots, the mutual coupling of slots in different waveguide can badly decrease the capability of wide-angle scanning of array. For this reason, an L-band HPM waveguide array of longitudinal shunt slots was designed. The choke groove was adopted to restrain the mutual coupling of slots of the HPM array antenna. The results of simulation are: the scanning angle of array without choke groove structure with the gain of antenna decreased 3 dB is only 24.7°, and it is 33.0° for array with choke groove structure; the wideband of active reflection of array have been improved with choke groove structure, the bandwidth of VSWR ≤3 of array with choke groove is 6.6%, and that is 5.0% without choke groove; the power-handling capacity of array antenna with scanning angle of 35° can reach 957 MW, which is a little less than that of array without scanning(1008 MW).
