Design and Analysis of Multiband Microstrip Patch Antenna Array for 5G Communications

Multiband microstrip patch antenna (MMPA) has several benefits, such as low cost, low profile, lightweight, easy manufacturing, and including conformance. To these feature's benefits, MMPA has become an essential part of today's wireless communication sector. On the other hand, poor performance occurs due to narrow bandwidth, low gain, low capacity, etc. In some cases, the aforementioned variables impose restrictions on antenna applications. In the nextgeneration wireless communication (5G) path loss will become a major issue to the use of high-frequency bands. This issue can be overcome by using a high gain antenna. The fundamental goal of the research is to design a high-gain MMPA array antenna. An MMPA is designed and simulated at CST Microwave Studio, the proposed antenna covers the following frequency bands such are 26.305 GHz, 29.125 GHz, and 37.78 GHz respectively. The foam material is chosen as a dielectric because its relative permittivity is about unity. The bandwidths of the multiband antenna are 815 MHz, 680 MHz and 584 MHz in separate bands, efficiencies at different bands are 88.205%, 83.713%, and 75.99%, with high gain of 13. 534db, 12.65db, and 10. 814db respectively.
