Latest Patents

Nakamata's latest patents include a bandpass filter, a high-frequency module, and wireless communications equipment. His bandpass filter features N (N≥2) resonators formed by laminating multiple conductor patterns and dielectric layers alternately. These resonators are arranged in an at least partially overlapped manner, allowing them to couple electromagnetically. The design includes input and output lines coupled to two selected resonators, with one end of each resonator grounded. The length of each resonator in the signal propagation direction is approximately λ/4, where λ represents the propagation wavelength inside the dielectric layers at the center frequency of the pass band. This innovative design achieves a wider pass bandwidth, size and loss reduction, and significant attenuation within a narrow band.
