Simply by loading the microstrip antenna at a suitable ( ) position using a single chip resistor, circular polarization CP radiation can be obtained with a single feed. In addition, this design can also pro¨ide an enhanced CP bandwidth. Results of the proposed CP design applied to circular and recta

The characteristics of a slot-coupled circular microstrip antenna with chip-resistor and chip-capacitor loadings are studied. With a chip-resistor loading, a significant decrease in the resonant frequency of the microstrip antenna is achie¨ed, which can result in a large antenna size reduction, and
