Low Cost, Low Side-Lobe Array of Waveguide-fed Microstrip Antennas
A low-cost,low side-lob Ku-band array of microstrip antennas,which is fed by waveguide,is presented in this paper.The 72 corner-fed square patches of the array are arranged in a 6-by-12 configuration.A novel waveguide to microstrip line transition with power divider is employed as a centre fed for the array in order to reduce the loss of the microstrip feed line.The gain of the array was measured to be 24.1 dB.The side-lob is below -20 dB and the return loss at resonant frequency is less than -25 dB.This array of waveguide-fed microstrip antennas can be used in many modern communication systems,such as a mobile radar sensor,in which the transition can be fixed as a connection between the module with a front-end waveguide and antennas.
