[origin: US5430417A] PCT No. PCT/DE92/00420 Sec. 371 Date Jan. 4, 1994 Sec. 102(e) Date Jan. 4, 1994 PCT Filed May 23, 1992 PCT Pub. No. WO93/01627 PCT Pub. Date Jan. 21, 1993.A matching network is to be provided which can quickly and easily be tuned to a desired impedance. The matching network has a first and a second line which are interconnected at one end, while their other ends are coupled to a microwave line, and a third line which branches off from the interconnection of the other two lines. The first and/or second line and the third line are loaded with ferrite. The ferrite of the first and/or second line and that of the third line are exposed to separate magnetic fields which can be varied independently of each other.
