This paper presents another alternative design of monopole microstrip patch antenna for millimeter wave (MMW) short range wireless communications applications. The purpose of this paper is to discuss a new design of antenna that operates in the MMW frequency range at 60 GHz. The design is based on single element with full size of 9  11 mm2 that contains two elliptical loops monopole antenna and a line feed of 50 ohm on the top layer of substate with a partial ground plane on the opposite side. Microstrip-patch antenna has been designed and implemented for 5G wireless communication technology at 60 GHz with low-cost and small size substrate that makes it suitable for small devices. In the proposed design, the used substrate material is Roger RT6035htc lossy with relative dielectric 3.5 and loss tangent 0.0013 with partial ground plane to improve the impedance characteristics. The designed antenna provides a uniform current distribution over the surface of antenna at the resonance frequency with an acceptable realized gain of 4.8 dBi in the far-zone with a return loss reaches up to – 33 dB. The simulation results are carried out using high frequency structure simulator (HFSS), FEM is based on full 3D wave electromagnetic solver simulator from Analysis and the obtained results confirm the suitability of the proposed MMW antenna to be a good candidate for 5G applications.
