Multiband Microstrip Patch Antenna for 5G Wireless Communication

Abstract

In current time's an immense proliferation occurred in the user's density of wireless communication, not so far but in near past one channel was enough for the necessities of a single mobile user. Now even 4G technology is inadequate to deliver its clienteles a wider bandwidth, gain and fast communication. For need of high hasten communication technology alteration is under way and is switching from 4G to 5G. For multi-channel communication necessity, communicating gadgets are integrated with multiple bands having peculiarity to work on disparate frequency channels in a single device. In this projected work microstrip patch antenna is used as communicating tool and analyzed for one band and dual band communication at higher frequencies (mm-waves). Microstrip patch antenna is selected because of its simple design, low price, compactness and compatibility with circuit elements. A dual band U-shaped slotted Microstrip patch antenna with 28GHz and 38GHz operating bands is presented in this paper. The total area of antenna is8.5 × 8 × 0.254í µí±ší µí±š 3 , the substrate used in designing is Rogers RT 5880 having a dielectric constant 2.2. The antenna resulted in return loss of-32dB at 28GHz and-40dB at 38GHz. The simulated gain of proposed dual band is 6.7dB at 28GHz and 7.92dB at 38GHz.
