Novel design of Microstrip patch antenna for mmWave 5G applications

Microstrip slotted patch antennas are drawing attention from antenna designer’s due to its appealing features such as less weight and low profile, but they also have certain drawbacks such as narrow bandwidth, low gain and higher VSWR (Voltage Standing Wave Ratio). These disadvantages can be overcome to some extent by proper study about the design of antennas and with right implementation of the design. This research offers a novel design for microstrip patch antenna bandwidth, efficiency, and reduction of VSWR using a slotted patch adjacent to the radiating patch. In this study, a microstrip slotted patch antenna is also suggested for 5G communication. The designed structure is a dual band antenna with operational frequency at 31.45 and 39.95 GHz which has the return loss as -29.234 dB and -34.541 and VSWR as 1.072 and 1.036 respectively. The proposed design is simulated using the CST studio suite (Computer Simulation Technology) software. The operational frequency with such narrowband is apt for high band 5G applications.
