Realization of Printed Rotated Slot Antenna With Tuning Stubs Fed by Microstrip Feedline for Bandwidth Enhancement

摘要

. To increase the impedance bandwidth a square patch at the centre of the rotating slot is embedded as a parasitic element. To compensate the return loss, rectangular slots are being cut in the square patch. Unifying tuning stubs to the feedline in high range of frequency introduces additional resonance. -10 dB impedance bandwidth for the proposed antenna is found to be 156.9% ranging from 1.13-9.35 GHz.
