Design Of Circular Slot Microstrip Patch Antenna With Thin-line Stub For Wideband And Multiband Wireless Applications
Parvathi K K, Dr. Haris P A
Abstract
In this paper, a circular slot microstrip patch antenna with a rotated square patch and two thin-line stubs attached to the back side of the antenna for enhancing bandwidth and operational effectiveness is presented. Results show that the antenna operates from 10.5GHz-18GHz with a reflection coeffi- cient of less than -10dB and obtains better bandwidth(7.5GHz). The gain of the circular slot antenna is 6.6dB, providing good per- formance when compared with the rotated square slot antenna. The antenna is suitable for wideband and multiband wireless applications such as radar and satellite.
