Abstract

In this paper, a compact slotted circular monopole antenna with spike shaped slots embedded in it is presented. Also, the proposed antenna has ground length limited to 33% of substrate length. This ground is provided on the back side of the antenna geometry to excite the antenna by microstrip line feed. A slotted circular patch element will be achieved by subtracting 45 degrees rotated square patch of 12mm x 12mm, and then by proper scaling. In this study the geometry is scaled separately by 60%, 40%, 20%, and finally the resultant is obtained by uniting them. This final geometry offers an ultra wide band operation. The overall size of the antenna is 30mm×32.4mm×1.6mm including finite ground feeding mechanism. The antenna operates in the frequency range from 2.5-15GHz covering FCC defined UWB band with more than 130% impedance bandwidth. Stable omni-directional radiation patterns in the desired frequency band have been obtained. Measured data fairly agree with the simulated results.
