Abstract

In this paper, a compact ultra-wideband antenna with filtering functions is presented. It has a compact size of 32mm*26mm*0.8mm. The filtenna is fabricated on a common and low-cost FR4 substrate, with a relative dielectric constant of 4.4, and a loss tangent of 0.02. With the use of an umbrella-shaped radiating element, and a modified ground plane structure, this filtenna meets a 10dB impedance from 2.8 to 12 GHz. By employing U-shaped slots on the feed line and on the ground, a stop band in 5.5GHz, also with high selectivity, is achieved. These electrical characteristics make it attractive for use in ultra-wideband (UWB) systems.
