EFFECT OF METALLIZATION THICKNESS ON MILLIMETER WAVE LEAKY-WAVE ANTENNAS
金属栅厚度对介质波导漏波天线辐射特性的影响

The effect of metallization thickness on a leaky wave antenna based on a metal-strip-loaded dielectric insert waveguide is investigated. The intrinsic equation is set up by. the extended version of the network analytical method of electromagnetic field. Numerical results show that the effect of metallization thickness is smaller on the direction of main beam and very noticeable on the beamwidth and aperture efficiency.
