Abstract :
A Compact printed UWB slot antenna with tuneable extra band is presented in this paper. The pentagonal slot antenna that covers the UWB band, 3.1 to 10.6 GHz, is fed by a semi circular patch. To create an extra band, an inverted U-shaped strip is attached to the upper part of the slot. By changing the length of this strip the resonance frequency can be adjusted from 1.5 to 2.4 GHz with little effect on the UWB performance of the antenna. The proposed antenna has compact size of 23 × 29 mm2 with stable radiation pattern both at the extra and whole of the UWB bands. A prototype of the antenna is fabricated and measured results are compared with the simulation.
