A low-cost Ku-band array of microstrip antennas, which is fed by standard waveguide, is presented in this article. The 72 corner-fed square patches of the array are arranged in a 6-by-12 configuration. A novel waveguide-to-microstrip transition with power divider is employed as the fed for the array

Abstract
In this letter, we present the 2 by 1 and 2 by 2 array microstrip patch antennas using the waveguide endwall coupler at 24 GHz. These antennas consist of a waveguide feed and two or four patches that are excited by the endwall coupler. As the measured results, the 2 by 2 array antenna has the gain of 10.7 dBi and the bandwidth of 1.3 GHz, and half power beamwidth is 31Β° on the Eβplane and 35Β° on the Hβplane. Because this transition technique is very simple and easy to fabricate, it can be used for low cost and high volume production for commercial millimeterβwave applications.
