摘要：
In this paper, a novel bandwidth-enhanced ultra-wideband (UWB) tapered slot antenna with Y-shaped corrugated edges, is proposed. In the double-slot structure, the two slots are separated by a V-shaped metal surface with straight edges, which is beneficial to improve the directivity of the antenna. Meanwhile, an exponential Y-shaped corrugated edge is designed. This novel corrugated edge can not only improve the impedance bandwidth, but also enhance the gain of the antenna. Additionally, according to the theory of microwave network, this paper analyzes the reason of bandwidth enhancement realized by double-slot structure. The proposed antenna provides 167% fractional bandwidth from 2.5 GHz to 28 GHz. The gain of the proposed antenna is more than 10 dB from 3.5 GHz to 25 GHz, and more than 8 dB at the whole operating band. (C) 2017 Elsevier GmbH. All rights reserved.
