摘要:
This invention offers a compact and high performance dielectric filter consisting of a quarter wavelength dielectric body provided with a through-hole between the upper and lower surfaces of the dielectric body, electrodes deposited on external and lower surfaces of the dielectric body, and at least two independent electrodes provided on an internal surface of the through-hole, extending to the upper and lower surfaces of the dielectric body. With this dielectric filter construction, the through-hole performs the role of constructing plural quarter wavelength resonators and performs, at the same time, the role of adjusting the coupling between the plural resonators, thus yielding a compact dielectric filter of simple construction.
