Design and Implementation of Microstrip Antenna array with Improved Gain for 5G communication

In this study, a microstrip array antenna for 5G communications is presented. Because there are so many satellite resources available and there is such a high demand for satellite communication, there is a need for extending the S band of the satellite frequency band in the communication industry. The attributes of the proposed antenna design, a rectangular and circular slotting in ground plane with circular and diamond slotted microstrip patch antenna. It operates at frequencies range of 2GHz and 4GHz (centered at 2.5GHz), with gain and directivity is 4.05dbi ,7.65dbi respectively. The patch is compact, inexpensive, and ideally suited for miniaturized equipment. It is made up of a copper (annealed) patch, a PEC, and a FR-4 (lossy) substrate with a loss tangent of 0.002 and a standard height of 1.6 mm from ground. The employed materials are a patch measuring 37mm by 28mm and a substrate measuring 65mm by 95mm. The technique of Microstrip feeding is employed. One technique for achieving this goal is Defected Ground Structure (DGS), One of the original methods for reducing the antenna size is the flaw in the ground. This antenna design is simulated at CST Microwave Studio. As a result, when designing an antenna with a defective ground construction, the antenna size is less for a given frequency than it would be with a perfect ground structure.
