R&D of High-gain and Beam-scanning Antenna Systems in THz band
Millimeter-wave and Teraherz-wave bands are expected to be used for many wireless applications in our life. We are in the development of high-gain beam-scanning antennas for automotive radar systems in 80GHz band and high-speed wireless communication systems such as beyond 5G/6G in 300GHz band by using electromagnetic simulators and measurement systems up to 330GHz band in this laboratory.

We have design and measurement techniques for waveguide-to-planar-transmission line transisions in the 300 GHz band. Since primary radiators such as lens antennas are fed from a waveguide, a transmission line transition is required to connect the transmission line on the substrate with high efficiency. In addition, the dielectric substrate and waveguide can be easily connected by using these transisions. Transmission loss of planar lines can be measured without using a prober station.
Planar Multibeam Antenna Systems in 300GHz band
We are in the development of planar multibeam antennas in 300GHz band. The size of the multibeam antenna can be quite small in the frequency band. Various beamforming circuits and planar arrays are currently going to be developed in our lab. We are also developing on a design using a low-loss substrate as research to improve transmission efficiency.
Design and Measurement Techniques of Dielectric Lens Antennas in 300GHz band
We have design and measurement techniques of low profile dielectric lens antennas with wide beam-scanning angle in 300GHz band. Optimization of lens curve and primary radiators to realize high gain and wide scanning angle. Low profile lens antennas have been developed by using high-permittivity resin with matching layer on the lens surface.
