This paper presents a novel G-shaped compact monopole UWB antenna printed on FR4 substrate with coplanar waveguide (CPW) feeding. The proposed antenna operates over the frequency band between 3 and 11 GHz offering a fractional impedance bandwidth of around 110 %. The antenna is designed by analysing the modal currents calculated using the characteristic mode theory. Experimental results on reflection coefficient agree well with simulations and the proposed antenna has a desirable gain and radiation pattern characteristics over the ultra-wideband frequency range. The overall dimensions of the antenna are 28 × 35 × 1.6 mm3 which makes it a good candidate for many ultra-wide-band radio applications.
