摘要：
A coplanar waveguide (CPW)-fed monopole antenna is proposed, which is composed of a rectangular monopole patch notched at the bottom, a T-shaped CPW ground in the notch, and a tapered CPW ground out of the notch. The simulated and experimental results show that the antenna achieves a fractional impedance bandwidth of 164% for S-11 <= -10 dB, which is about 2.3 times of the conventional one. The parametric studies and measured radiation characteristics are presented. The results show that the antenna exhibits good characteristics and is suitable for portable mobile ultrawideband (UWB) applications.
