Four Rectangular Shaped DRA Array for Wireless and Satellite Communication

Abstract

The purpose of this paper is to demonstrate that our proposed design, which consists of a four rectangular shaped dielectric resonator antenna (DRA) array, is capable of being used in a variety of microwave access applications. To reduce return losses and simplify fabrication, the microstrip feed line method is used. We were able to put our concept into action by fabricating it on a sheet of Roggers RT Duroid 5880. The current proposal earns approximately 25%, 40%, and 22.2 percent impedance bandwidth, respectively, from 2.4 to 2.6 GHz, 2.7 to 3.1 GHz, and 5.4 to 5.6 GHz, covering 2.4 GHz, which is a Bluetooth band, 2.9 GHz, which is primarily used for Wi-Fi applications, and 5.2 GHz, which is a WLAN band. DRA's average peak gain is 7.4 dBi at 2.4 GHz and 8.33 dBi at 2.9 GHz, respectively, with directivity ranging from 3.47 dBi to 10.8 dBi over the entire frequency range. At the resonant frequencies the proposed DRA array gives the enhanced gain and better radiation characteristics. The prototype model can also be used for 5.15 GHz to 5.30 GHz which is an operating range of HIPERLAN (high-performance radio LAN) applications. Simulation of the proposed design is performed using CST microwave studio software and a close difference has been noted between the simulation and measured results
