Superstrate Microstrip Antenna for 5G Wireless Communication Applications

In today’s era, the coexistence of human-centric and machine-type applications will lead to a large diversity of communication characteristics. Some of these applications can be supported by today’s mobile broadband networks and their future evolution. However, some other applications will impose additional and very diverse requirements on mobile and wireless communication systems that the fifth generation (5G) will have to support various requirements for different stakeholder like 5G new radio technology. This paper contributes the design of planar superstrate antenna for 5G NR frequency bands (b41/n41) for USA, China and South Korea as well as sub-millimeter wave application. The proposed antenna is resonated at three resonant frequencies 2.5, 5.2, and 7.08 GHz respectively and provides more than 500 MHz bandwidth. Moreover, the antenna is designed on Fr4 substrate material having a dielectric constant 4.4 and loss tangent, which is very cost effective. The achieved gain and radiation efficiency for the proposed antenna are more than 2 dB and 85% respectively. The total volume occupied by the antenna is 28 × 26 × 1.6 mm. The simulation has been carried out using Computer simulation Technology (CST) software.
