  • Abstract
    A simple and compact design of dual-band slot antenna is presented. Fed by a CPW, the antenna is printed on a single-layer PCB with extremely low manufacturing cost. A pair of T-match stubs is employed to generate the dual resonances in the 2.4-2.5 and 5-6 GHz bands. The antenna of small radiating area 11×28 mm2 is demonstrated on an FR4 PCB with ground plane size of 31×35 mm2. Robust radiation performances are achieved, including in-band gain flatness within +/- 0.5 dB and polarisation isolation better than 15 dB. Consistent radiation patterns for both bands are obtained with peak gains about 3 and 4 dBi in the lower and upper bands, respectively.
