摘要

本文提出了一种工作频率为1.7GHz的新型矩形漏波导，该漏波导的侧壁有一对倾斜的周期槽，可产生偏转辐射场。采用近场计算全波法和远场计算积分法相结合的混合方法分析了辐射特性。结果表明，通过合理设计狭缝参数，可以获得沿泄漏矩形波导的偏转辐射场。这种泄漏矩形波导可以应用于轨道交通系统中，它可以增强接收信号，抑制干扰。从而提高系统的可靠性。

Leaky rectangular waveguide with deflected radiation field

A novel kind of leaky rectangular waveguide with a pair of inclined periodic slots cut in the broadside wall, working at 1.7GHz, is presented in this paper, which can generate a deflected radiation field. The radiation characteristics are analyzed by a hybrid method combining a full-wave method for near-field computation and an integral method for far-field computation. Results show that a deflected radiation field along the leaky rectangular waveguide can be obtained by properly designing the parameters of slots. This kind of leaky rectangular waveguide can be applied in rail transportation system, it will enhance the receiving signal and suppress the interference. As a result, the reliability of the system will be improved.
