Abstract
A high-frequency module which includes a dielectric resonator defined by a dielectric sheet; a pair of electrodes formed on each of the main surfaces of the dielectric sheet and having aligned openings which form a dielectric resonator; a substrate stacked on the sheet; and lines disposed on the substrate for being coupled to the dielectric resonator. At least one of the lines is curved and is disposed just inside the opening and runs substantially along the edges of the openings.
Claims21
A high-frequency module comprising:
- a dielectric sheet having two opposed main surfaces;
- electrodes disposed on both main surfaces of the sheet;
- a pair of openings formed respectively in the electrodes and having corresponding aligned edges so as to provide a dielectric resonator;
- first and second conductive lines disposed on a substrate, said substrate being stacked on said dielectric sheet, said lines being magnetically coupled to the dielectric resonator;
- and
- a conductive case containing said substrate and said dielectric sheet;
- wherein said first line has a first portion arranged along a path which runs substantially along said edges of the openings.
