Abstract
This paper introduces a microstrip square patch antenna with a novel low-cost and efficient feeding mechanism for millimetre-wave frequencies targeting at 28 GHz. The radiating patch is excited by the technique of empty substrate integrated waveguide, and two different slot configurations have been examined in this regard. It has been observed that the antenna gain profile and radiation efficiency is significantly improved in both configurations as compared to the microstrip square patch antenna provided with conventional feeding.
