Design of Efficient 37 GHz Millimeter Wave Microstrip Patch Antenna for 5G Mobile Application

Millimeter wave (mmWave) wireless technology has become a part of human life for high-speed and secure data transmission. This paper presents a square-slotted microstrip patch antenna at 37 GHz resonant frequency for mmWave wireless communication. The antenna consists of one H-slot and one inverted T-slot loaded over the radiating patch. The proposed antenna has been designed and investigated on Rogers RT5880 substrate with relative permittivity 2.2 and loss tangent 0.0009 using Electromagnetic Simulation Software CST Microwave Studio. The result of this paper shows minimal return loss −43.05 dB, gain 8.18 dB, and impedance bandwidth 16.22% at 37 GHz resonant frequency. The voltage standing wave ratio (VSWR), E-plane, and H-plane radiation pattern has also presented for the proposed antenna which can be strong candidate for 5G mmWave cellular communication.
