Design and Analysis of A Ka Band Microstrip Slotted Patch Antenna with 5G Communication Technology Using CST

Microstrip slotted patch antennas are drawing antenna designers' attention due to appealing features such as less weight and low profile, but they also have certain downsides such as low gain, narrow bandwidth and higher VSWR (Voltage Standing Wave Ratio). These disadvantages can be mitigated to some extent by careful antenna design. This research offers a novel design for microstrip patch antenna bandwidth augmentation, efficiency and reduction of VSWR using a slotted patch adjacent to the radiating patch. A microstrip slotted patch antenna is also proposed for 5G communication in this study. The designed structure operates at 29.416 GHz. The proposed design is simulated using the CST studio suite (Computer Simulation Technology) software. The return loss is -44.78 dB, the bandwidth is 900 MHz and the VSWR is 1.0115. The findings demonstrate that the proposed design has favorable properties for Ka-band applications.
