Abstract

A dual-band two order filtering antenna is designed to cover both the GSM900 and GSM1900 bands. The resonator of the two order filter containsa half wavelength open-loop resonator and a T-shaped open stub. The antenna is composed of two parts. One is a printed monopole which covers lower frequency band, and the other is a strip with slot protruded from the ground plane, which covers higher frequency band. By substituting the antenna for the last resonator of the filter, the filtering antenna owns not only a good radiation function but also a good character of filter at the two working frequency bands.
