Design Of Rectangular Dielectric Resonator Antennas For C Band Wireless Communication Applications

Abstract

The evolution of antenna design in wireless communicationsystems deserves crucial attention, as it has seen rapid strides in theadvancement of technology in the 21st century. This rapid progress hasmade data transfer an integral part of our daily lives. The demand forhigher data rates and systems in wireless communication is driving therise of high-performance equipment, leading to a demand for compact,robust, wide-band, and highly efficient antennas. However, there is alimit to the available bandwidth and power transfer, which must beconsidered as we continue to push the limits of wireless technology. Microstrip antennas, including patch, slot, and printed dipole antennas, emit unwanted radiation due to dielectric and conductor loss. As a result, there is lower efficiency, lower gain, and more crosspolarization radiation in microstrip patch antennas. Also, there is decreased power handling and a smaller impedance bandwidth. On the other hand, the dielectric resonator antenna (DRA) offers much superior gain and a broader impedance bandwidth by using optimization methods.mAs a result, there is a lower loss of radiation compared with microstrip antennas. It is also easier to process and shape. This thesis aims to create rectangular dielectric resonator antennas (RDRAs) for C-band wireless communication applications. Their compact size, light weight, ease of design, high gain, and efficiency make them more suitable for WLAN, WiMAX, Wi-Fi, GPS, and mobile communication systems. While technological advancements can help minimize the antenna size, there are some design constraints too. Overwhelming all these limitations of proper design, we see that rectangle DRAs are being widely used in wireless communication equipment. newline newline
