Abstract

A compact and simple design of a CPW-fed planar antenna for ultra-wideband application with a band-notch characteristic is presented. The proposed antenna consists of a rectangular metal patch on a printed circuit board fed by a 50Ω coplanar waveguide (CPW) with an overall size of 32×30×1.6mm³. By cutting a C-shaped slot in the rectangular radiating patch, a frequency band notch will be created. The proposed antenna yields an impedance bandwidth of 3.1-10.6GHz with VSWR≤2, except the bandwidth of 5-6GHz for WLAN. The bandwidth and central frequency of the notched band can be adjusted with ease by proper selection of C-shaped slot. The parameters simulated by CST Microwave Studio. The antenna is successfully designed and simulated. Showing broadband matched impedance, stable gain and radiation patterns over an operating bandwidth.
