摘要：

A new configuration of three slots is proposed to radiate a 45 degrees linearly polarised wave in post-wall waveguide-fed parallel plate slot arrays. The configuration consists of one radiating slot tilted to give the desired polarisation and two parallel lambda /2-spaced reflection-cancelling slots without radiation in the boresight. A uniform aperture field is designed in a 76GHz antenna. A good cross-polarisation level below -28dB is achieved in the boresight. A gain of 29.8dBi is obtained with 46.4%, efficiency in a 5cm square antenna.
