Abstract

The Substrate Integrated Waveguide (SIW) cavity is one of the cavity-supported slot antennas that use substrate SIW technology and 5G application. The proposed model antenna operates at 26 GHz-46 GHz frequency range. The proposed model resonates at 33.84 GHz and 40.28 GHz frequency range. The use of substrate-integrated waveguide (SIW) cavity offers low cost, easy implementation, high gain, and self-consistent electrical shielding. Existing dipole and monopole antennas have some limitations, such as lack of potential ability, low capability and high mutual coupling. The modified semicircle-shaped rectangular patch is intended on a Rogers RT6002 substrate with the dimension of 26 mm × 26 mm × 0.762 mm and dielectric constant of 2.94. To increase the gain of the antenna, a SIW cavity is placed on top of the patch. A Meta Absorber is added on the left and right sides of the patch to reduce electromagnetic interference, provide excellent absorptivity, and improve antenna performance. A coplanar waveguide (CPW) feed line is added to the bottom of the patch. A coplanar waveguide (CPW) feed line offers high-speed data rates and low latency in a 5G mm wave application. The suggested model obtains enhanced simulated and fabricated performances related to traditional antenna models. The suggested model antenna obtains enhanced simulated and fabricated performance compared to traditional antenna models. The fractional bandwidth of the proposed antenna achieves a fractional bandwidth of 59%.
