Abstract

A compact ultra-wide band (UWB) (3.1-10.6 GHz) monopole antenna that can be integrated in ultra-wide band mobile terminals is designed in this paper. The antenna consists of a rectangular radiating patch and a gradual transformer, and is fed by a co-planar waveguide which supports a quasi-TEM mode of propagation with low dispersion. The antenna is then modified to possess band rejection at the wireless local area network (WLAN) (5.1-5.8 GHz) frequency band by etching a pair of slots within the radiating patch. Simulated and measured results are shown to demonstrate the performance of the antenna.
