摘要

在本文中，我们提出了一种用于头部成像系统的宽带贴片天线。它由贴片和地面组成，与普通贴片天线相比，这两种结构在很大程度上是token off的。通过对该天线结构的分析，可以得出其频带主要由三个参数控制。大量的仿真结果表明，在1.23 ~ 2.63 GHz频率范围内，贴片天线提供了−10 dB带宽为71.1%的宽带工作。此外，在整个工作频率下，辐射方向图几乎是双向的，增益都在3 dBi以上。

Design of Wideband Patch Antenna for Microwave Imaging Systems

In this letter, we propose a wideband patch antenna for the head imaging systems. It is composed of a patch and the ground, and both structure are largely token off in comparison with normal patch antenna. By analyzing the structure of this antenna, we could obtain the band is mainly controlled by three parameters. Extensive simulations demonstrate that patch antenna provides wideband operation with −10 dB bandwidths of 71.1% at the frequency of 1.23 – 2.63 GHz. Moreover, the radiation patterns are almost the bi-directional and the gains are all above 3 dBi at entire operation frequencies.
