Abstract:

In order to broaden the bandwidth of a tapered slot-line antenna(TSA), a bilateral tapered slot-line antenna(BTSA)with a new feeding structure of coplanar waveguide(CPW)is developed. Based on the fact that the bandwidth limitation of TSA mainly depends on its feeding structure, an improved CPW-based feed structure etched on the backboard of the BTSA is adopted to perform traveling-wave transition. Both the simulation results and measurement data verify that the proposed feeding structure results in “high-pass” frequency response for antenna impedance matching. The voltage standing wave ratio(VSWR)is less than 2∶1 when the frequency is higher than 3 GHz. The antenna gain exceeds 7 dBi with good radiation patterns when the bandwidth is from 4 to 16 GHz. This ultra wideband(UWB)antenna with a compact size is specially available for the electronic systems of counter-measure and microwave imaging.
