Abstract

In this paper, a miniaturized CPW-fed tapered slot antenna (TSA) with a modified CPW to slot-line transition structure was introduced. An air-bridge and tapered slot edge (TSE) structure was also employed to broaden the transition bandwidth. Through these applied modifications, negative features of the original TSA (limitation of transition) and antipodal Vivaldi antenna (bad cross-polarization) are both removed, while all the positive features remained. Results showed that the proposed structure offered a broad bandwidth of 2.6–20 GHz and also exhibited an appropriate current distribution with high radiation efficiency. The radiation pattern was stable in the working frequency band with good directivity, gain, and low cross-polarization. The proposed antenna structure also presented satisfactory time-domain characteristics. In this study, we confirmed the simulation results through data measurements.
