A low‐cost, low side‐lobe Ku‐band array of microstrip antennas, which is fed by 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 line transition with power divider is employed as a center fed for the array to reduce the loss of the microstrip feed line. The measured gain is 24.1 dB. The side‐lobe is below −20 dB, and the return loss at resonant frequency 12.5 GHz is less than −25 dB. © 2010 Wiley Periodicals, Inc.
