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.
