Abstract

A novel millimeter wave monopulse slotted waveguide array antenna with a central hole for infrared sensor use is presented. The amplitude distribution is optimized, and a monopulse comparator is designed to feed the proposed array. This millimeter wave array antenna has been fabricated and measured. The gain of the sum beam is higher than 32dB, whereas the zero depth of the difference beam is lower than -28dB. The side-lobe level is -15.0dB in E-plane and that in H-plane is -13.0dB.
