摘要

A new compact dual wideband CPW-fed inverse triangular-shape antenna is presented. The lower and upper bands are widened from 68.76 and 18.33% to 96.23 and 28.7%, respectively, using a triangular patch-trapezoidal ground combination. The antenna performance is further enhanced by backing it with a dual-band uni-planar EBG reflector. The final design has been prototyped and measured. It sufficiently covers the frequency bands 1.5-5.63 GHz and 9.52-13.06 GHz with enhanced gain up to 5.2 dB. The radiation efficiency is improved to approximately 72%.
