Abstract
In this paper, a monopole antenna with triangular shaped patch based on coplanar waveguide (CPW)-feed is presented. The proposed antenna comprises a planar triangular patch element with a staircase ground which offers ultra wide bandwidth. The impedance bandwidth can be tuned by changing staircase shaped ground parameters (number of steps, step length, and/or its width). The overall size of the antenna is 28mm×26mm×1.6mm including finite ground CPW feeding mechanism. The antenna operates in the frequency range from 3.2-12GHz covering FCC defined UWB band with more than 100% impedance bandwidth. Stable omni-directional radiation patterns in the desired frequency band have been obtained. Measured data fairly agree with the simulated results.
