A novel compact CPW ultra-wideband (UWB) antenna combined with a compact band-selective filter is proposed. The proposed antenna without filter satisfies the return loss requirement of less than −10 dB over the frequency range of 3.0 GHz to 12.1 GHz. The optimized antenna has dimensions of 10×16 mm 2 on a Teflon substrate (ε r = 3.48) with good radiation characteristics and is easy to fabricate. The proposed antenna with filter has the frequency band of 3 GHz to 11 GHz for VSWR less than 2.0 with a rejection band around 5.0 to 5.9 GHz.
