CPW Fed Ultra Wideband Strip Antenna

A compact CPW-fed planar monopole antenna for UWB applications is presented and investigated. The proposed antenna with a size of 17.7 mm × 26 mm × 1.6 mm fed with a CPW feed and a slotted ground plane is developed. The antenna yields a -10dB bandwidth ranging from 3.1 to 10.6 GHz with monopole like radiation pattern and stable gain. Design equations for the proposed antenna are derived and validated with different substrates. From the investigation of frequency domain and time domain characteristics, it is observed that over the entire operating band, antenna exhibits good transient characteristics.
