Abstract:
PCT No. PCT/FI88/00163 Sec. 371 Date Jun. 12, 1990 Sec. 102(e) Date Jun. 12, 1990 PCT Filed Oct. 7, 1988 PCT Pub. No. WO89/05046 PCT Pub. Date Jun. 1, 1989.The invention relates to a resonator structure comprising a helix resonator (1) wound of metal wire into a cylindrical coil and supported by a plate (2) of insulating material disposed therewithin. A helix resonator is usually made in the form of a cylindrical coil and supported by disposing within the coil a frame made of a ceramic material or plastic in various ways. This is necessary for providing a sufficient mechanical strength. However, such a structure is difficult and expensive to manufacture in series production especially with smaller resonator sizes. These problems are solved by means of a resonator according to the invention in such a manner that at least a part of the insulating plate (2) comprises an electrical circuit formed by strip lines (3), and that the helix resonator (1) is electrically connected to said circuit.
