摘要：

A compact monopole antenna with enhanced bandwidth and triple band rejections for ultra-wideband applications is presented. The base of the proposed antenna is a semicircular patch which is fed by a modified tapered coplanar waveguide line. By using the trident-shaped feed line, much wider impedance bandwidth is obtained. To avoid potential interferences, two trapezoid stubs and a C-shaped stub are printed on the back surface of the substrate and are connected to the antenna through three vias. The proposed antenna is practically fabricated with a compact size of 20 x 24 mm(2). Good agreement is achieved between the simulation and measurement, which shows that the proposed antenna offers a very wide bandwidth from 3.02 to 20.8 GHz (149%) with triple band rejections covering the 3.5 GHz WiMAX and 5.2/5.8 GHz WLAN bands.
