Improving Bandwidth & Gain using Trapezoidal Microstrip Feed with X-Shape DRA

Abstract

As microwave technology develops, the dielectric resonator antenna (DRA) is being employed more and more in point-to-point communications systems. Their research supported the notion that dielectric resonator antennas are desirable alternatives to conventional low-advantage antenna factors, together with microstrip patches, monopoles, and dipoles. This article uses an X-shaped DRA to excite a microstrip line with a trapezoidal form. This arrangement increases impedance bandwidth by 78%. The highest advantage of those antennas, which cover the c-band (48GHz) of the electromagnetic spectrum, is 6.8dB. Wi-Fi routers, telecom, aerial navigation structures, marine radio navigation structures, and other weather radar systems are some of the applications for this antenna.
