A 1-D Beam Scanning Planar Dielectric Lens Based On A Phase-Center Electrically Controllable Primary Feed
2019 13TH EUROPEAN CONFERENCE ON ANTENNAS AND PROPAGATION (EUCAP)(2019)
摘要
A primary feed with electrically controllable phase-center is proposed and utilized in a 1-D beam scanning planar dielectric lens. First, a method to synthesis design the feed with specific phase-center positions is demonstrated. Then, the physical realization of the feed is displayed. Finally, it is located at the focal plane of a well-designed 1-D planar dielectric lens, so as to obtain the beam scanning performance. The simulated results indicate that the beam scanning property has been observed and the largest scanning angle of the designed lens antenna is +/- 6 degrees at 5.5 GHz. The proposed design theory and design method have thus been validated.
