A Novel Design Of Grid Microstrip Monopulse Antenna

Abstract

This letter introduces a novel design of grid microstrip monopulse antenna, and the simulation results of VSWR and radiation pattern are given respectively. The radiation element of the antenna is in the form of grid microstrip. The taper distribution of the array surface is required by the different width of the microstrip radiation element, which overcomes the shortcomings of the traditional waveguide slot antenna, such as the complexity of design and the high precision of processing, and the implementation is relatively simple. The antenna is divided into two parts, radiation array and differential feed network. The simulation results show that the antenna has a bandwidth of 2.8% (VSWR is not more than 2) and an amplitude lobe performance of - 20dB. The size of antenna array is 5.1 λ * 5.1 λ
