High Gain, Compact Design Integrated With FSS As Superstrate In Patch Antenna For Sub6 Ghz 5G Application

In the field of radio engineering, an antenna is essential. A transmitter or receiver is used to connect the network between radio waves that travel across space and electric currents that travel via metal conductors. In 1953, the first patch antenna was created. However, because of their positive characteristics, such as low profile, affordable production, lightweight, and simple installation, they also became the researcher's focus area. This study indicates a compact rectangle-shaped microstrip patch antenna. Very first a rectangular shape patch antenna together with dimensions of 30x35 mm

at 6 GHz is created utilizing an Fr4 substrate with 4.4 permittivity and a height of 1.6 mm. The simulated result showed an acceptable reflection coefficient, VSWR, and high gain with the integration of the FSS layer as a superstrate. FR4 material is used to create a unit cell for an FSS periodic structure with a 6x7 array. The simulated outcome displays a broad bandwidth between 3.2 GHz to 6.5 GHz with an increase in gain from 4 dB to 7.5 db.
