| Abstract(in English) | Broadband antennas which cover wide angular area with high gain are expected for high-speed huge-capacity wireless communication systems and wireless sensing systems in 300GHz band. Lens antennas perform low feeding loss even for high gain in such a frequency range. Electric beam-scanning is possible by switching primary radiators arranged around the focus of the lens. However, crossover level drops down significantly when the beam width is narrow due to the limitation of the size reduction of the primary radiators. Thus, two ways to prevent dropping down the crossover level are proposed in this paper. One is to feed primary radiators simultaneously and synthesizing in phase toward the required direction instead of switching. Another one is to increase gain by array configuration of small aperture lenses with higher crossover level and synthesizing in phase toward required direction instead of one large-aperture lens antenna. Transmission line transitions to connect RFIC and waveguide feeding horn antennas for primary radiators of lens antennas are also proposed in this paper. |
