Abstract

In this paper, a bowtie antenna using a broadband microstrip to coplanar stripline transition balun is proposed. This antenna with a new transition structure has several advantages such as small size, wide bandwidth, and good impedance matching. In the balun of this antenna, the low impedance of the mircrostrip lines is gradually transformed to the high impedance of the CPS by a tapered bottom strip line. The proposed antenna was designed and fabricated on Teflon substrate for bandwidth from 2.2 GHz to 6 GHz. The measured return loss is less than 10 dB from 2.1 GHz to 6.5 GHz. The measured gain is from −4.5 dBi to 2.4 dBi.
