摘要：

One type of magnetic coupling filter using skew-symmetric feed structure call create two transmission zeros in the upper stop-band. The mixed coupling filter call generate one transmission zero lying on each side of the passband and the S It spectrum is slightly asymmetrically shaped in the vicinity of the center frequency. A two-pole hexagonal magnetic coupling filter using skew-syninietric feed structure is designed and fabricated. The filter has a fractional bandwidth of 3% at 2.45 GHz. The transmission zeros are obtained in the tipper stopband at f(1) = 2.63 GHz and f(2) = 2.97 GHz. (c) 2007 Wiley Periodicals, Inc.
