This article presents a simple antenna array for millimeter‐wave communications at 28 GHz. The proposed antenna array is 40 × 19.22 mm 2 in size and operates in a measured 26.04 to 30.63 GHz frequency range. The antenna array elements are excited by a planar four‐way feed network, which has been designed and optimized for optimum performance. The single element of the proposed antenna array is a rhombic monopole surrounded by a series of vias, square parasitic patches were etched on the back side to enhance its impedance performance. The proposed antenna array has a peak gain of 11.24 dBi with radiation efficiency more than 85% in its entire operating band. Both single and its 4 × 1 array have been modeled, simulated, and fabricated using standard PCB process. Excellent agreement exists between the simulated and measured results. The antenna's simple design, compact size, and low fabrication cost, enables it to be deployed in millimeter‐wave communication systems.
