Abstract

This article presents a design of a single-polarization, 4 x 4 microstrip patch antenna array, operating at the K-a-band. An integrated microstrip network with the aid of using feeding probes excites the antenna array. Simulation and measurement results show that the array operates in a wideband frequency range (return loss RL >= 15 dB) from 32 to 36.4 GHz with a low sidelobe level (SLL
