摘要

介绍了一种用于超宽带医学成像系统的对映维瓦尔第天线。设计中采用了一种新的高阶功率指数函数，测量结果表明，该天线在1GHz ~ 12ghz范围内的带内回波损耗低于-10 dB。实验结果表明，该天线能够收发非常窄的脉冲，可用于医学成像系统。

An antipodal vivaldi antenna for ultra wideband medical imaging system

An Antipodal Vivaldi Antenna to be used in ultra wideband Medical imaging system is presented in this paper. A new high order power exponential function was used in the design of the proposed antenna, and the measurements showed that the in-band return loss is below -10 dB from 1GHz to12GHz. The experimental result indicates that the antenna is capable of sending and receiving very narrow pulse, which be used in Medical imaging system.
