Abstract (in Japanese) (See Japanese page) 
(in English) The high-frequency phase shifter is an essential core component of phased array systems, which adjusts the phase of signals to achieve beam forming and control. However, phase shifters that can simultaneously provide low loss and phase shifting of more than 360° are very rare in the market. It is necessary to seek new design solutions to improve the performance of phase shifters.
Recently, we have developed a new design method for low-loss phase shifters that can achieve a phase shift range greater than 360° and a loss of less than 1 dB. This innovative design not only improves the performance of phase shifters but also brings broader prospects for the application of phased array systems.This new design method for low-loss phase shifters can be applied in wireless power transfer, radar, and communication fields, especially in applications that require high-precision directional control and long-distance signal transmission.
