摘要

设计了一种工作频率为1.65 GHz ~ 18 GHz的椭圆锥形对足维瓦尔第天线，用于微波成像。它包括顶部和底部散热器的梳状狭缝和打开椭圆率，以降低常规对对维瓦尔第天线的频带限制。结果表明，在较低的频率下，梳状狭缝可以提高天线的增益，在2ghz频率下可达9.5 dBi，在18ghz频率下可达14.2 dBi。并论证了该天线应用于微波成像技术的可行性。

UWB elliptically-tapered antipodal Vivaldi antenna for microwave imaging applications

An elliptically-tapered antipodal Vivaldi antenna with operating frequency range from 1.65 GHz - 18 GHz designed for microwave imaging applications is presented. It includes comb-shaped slits and opening elliptical rate of top and bottom radiators to lower frequency band limitation of conventional antipodal Vivaldi antenna. It is shown that the antenna gain has been increased by comb-shaped slits at lower frequencies up to 9.5 dBi at 2 GHz and at higher frequencies up to 14.2 dBi at 18 GHz. Feasibility of the proposed antenna for the use in microwave imaging technique is also demonstrated.
