A new method for enhancing the 2:1 VSWR impedance bandwidth of microstrip antennas is presented. Bandwidth enhancement is achieved by loading the microstrip antenna by a ceramic microwave dielectric resonator (DR). The validity of this technique has been established using rectangular and circular radiating geometries. This method improves the bandwidth of a rectangular microstrip antenna to more than 10% (≈5 times that of a conventional rectangular microstrip antenna) with an enhanced gain of 1 dB. © 1998 John Wiley & Sons, Inc.
