Bandwidth Enhancement of Microstrip Line and CPW-Fed Asymmetrical Slot Antennas
By
Progress In Electromagnetics Research Letters, Vol. 32, 69-79, 2012
Abstract
In this paper, a bandwidth enhancement technique of asymmetrical slot antennas with two different excitation methods is presented. One method of excitation is the microstrip line feed, and the other is the coplanar waveguide feed. The rectangular slot excited by microstrip line feed gives an impedance bandwidth of 14.76% (|S11| < −10 dB). When the rectangular slot is excited by a coplanar waveguide (CPW), it gives an impedance bandwidth of 26.61%. Both impedance and radiation characteristics of these antennas are studied.
