High-frequency filter with dielectric substrates for transmitting TM modes in transverse direction

摘要

A high-frequency filter consists of a housing, which includes resonators, each of which has at least one dielectric. The n resonators are arranged along a central axis. The n resonators are isolated from one another by at least n−1 isolation devices. The n−1 isolation devices have coupling openings, through which a coupling is established at a right angle to or with one component predominantly at a right angle to the H field. A first signal line terminal is inserted into the first resonator chamber through a first opening in the housing and is in contact with the respective dielectric there. In addition or alternatively, a second signal line terminal is inserted into the n^th resonator chamber through a second opening in the housing and is in contact with the respective dielectric there.
