Abstract :
A dual-band planar-slot antenna that operates through a single coplanar waveguide (CPW) port in two 10% wide-frequency bands, one octave apart is presented. An input T-match circuit is used to match the antenna in both bands, without increasing its size and keeping the CPW feed advantages. A case antenna covering the two Global System for Mobile communications bands (0.88-0.96 GHz and 1.71-1.88 GHz) and the Digital Enhanced Cordless Telecommunications band (1.88-1.9 GHz) has been designed, built, and measured, to demonstrate the technique. A proprietary program, based on the method of moments, has been used to analyze and optimize the antenna.
