  • Bandpass filter, electronic device including said bandpass filter, and method of producing a bandpass filter
    Patent number: 7619495
    Abstract: The bandpass filter comprises transmission line comprising a conductor strip (2), and, in said transmission line, at least one bandpass filter cell, comprising at least one split-rings resonator (6, 7), inductive element (4, 41) and capacitive element (3). The bandpass filter has a frequency response in which at least one passband can be identified. The conductor strip, split-rings resonator(s), inductive element(s) and capacitive element(s) are dimensioned and arranged so that the bandpass filter, for frequencies within said passband, behaves as a left-handed transmission line for at least one range of frequencies within said passband, and as a right-handed transmission line for at least another range of frequencies within said passband, thus providing for a large bandwidth. The invention also relates to an electronic device including the filter, and to a method of producing it.
