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.

毫米波（mmWave）无线技术已成为人类生活中高速和安全数据传输的一部分。本文提出了一种在毫米波无线通信中谐振频率为37 GHz的方槽微带贴片天线。天线由一个H形槽和一个反向T形槽组成，它们安装在辐射贴片上。使用电磁仿真软件CST Microwave Studio在相对介电常数2.2和损耗角正切0.0009的Rogers RT5880基底上设计并研究了拟议的天线。本文的结果表明，在37 GHz谐振频率下，最小回波损耗−43.05 dB，增益为8.18 dB，阻抗带宽为16.22％。电压驻波比（VSWR），E平面，
