Abstract(in English) | In ITS services, antennas are required beam scanning ability. Authors designed a lens antenna that could achieve beam scanning over ±30°. Narrow beam widths were maintained on the scanning planes. However, beam shapes were distorted on the transverse planes. The reason of this beam distortion was due to the phase delay on the aperture. In this paper, a cluster feed composed of a group of rectangular horns is proposed. In order to achieve a phase delay correction, a new radiation pattern synthesis method is developed. Resultant excitation coefficients of the cluster feed horns are shown. And the phase correction in the radiation pattern of this feed is clarified. At the beam scanning angle of 30°, the beam shape on the transverse plane is improved to almost same as the beam on the scanning plane and the increase of antenna gain by 1.9dB is achieved. |
