Abstract

A compact ultra-wideband antenna fed by coplanar waveguide is reported in this paper. The designed antenna consists of a trumpet-shaped planar radiation patch and a symmetrical ground patch. Two Mickey-Mouse shaped perturbative slots and two quarter-elliptical grooves are etched on the ground to obtain better impedance matching. By prolonging the radiation patch, a very wide −10 dB bandwidth of covering 300 MHz-18 GHz with bandwidth ratio up to 60:1 and omnidirectional coverage are achieved. Furthermore, the proposed antenna is able to cover P(0.3-1G), L(1-2G), S(2-4G), C(4-8G), X(8-12G), and Ku (12-18G) bands, which is much preferred for wideband spectrum monitoring.
