Multi Band Microstrip Patch antenna for C band, X band and 5G Cellular Systems

Abstract

In this proposed work, a multiband microstrip patch antenna is designed which successfully demonstrated wideband characteristics. This design is envisaged to support 28 GHz frequency which is allocated by ITU for 5G mobile communication along with C (4-8 GHz) and X band (8-12 GHz) frequency supported applications. This design is primarily aimed to operate in 28 GHz and 38 GHz. The use of Defected Ground Structure (DGS) with two slots of dimension 1.5mm×1.5mm made this model to operate in multiband frequencies which includes 4 GHz, 9 GHz, 28 GHz and 38 GHz. The designed antenna is placed on a material called FR-4(flame retardant) whose dielectric constant (Ɛr) equals to 4.3 and the size of the substrate is 10.8 mm×12.9 mm which is known to retain its high mechanical value. The antenna is simulated and optimized with the aid of CST (Computer Simulation Technology) software a specialized tool for the 3D EM simulation of high frequency component. From the simulated results it have been shown that the proposed antenna is suitable for C band, X band and 5G wireless applications.
