In order to attain such an object, three or more top end open stubs, which are set to have a large electric length in a range in which a length of is shorter than ¼ of a wavelength of a pass frequency, are disposed substantially in parallel so that their respective open ends face an identical direction to thereby form a combined line, and a high impedance line that is shorter than the wavelength of the pass frequency is connected to at least one part among parts between neighboring ends on the opposite side of open ends of the top end open stubs.

摘要： A low-pass filter includes metal stub conductors mounted on a signal conductor at midpoints of adjacent high impedance sections of the signal conductor. The metal stub conductors prevent the occurrence of resonance between the high impedance sections, thereby providing a large attenuation value over a wide frequency band above the cutoff frequency of the low-pass filter.

摘要： An object of the present invention is to provide an antenna feeding circuit, which requires no balance-unbalance converter and has a simplified structure. The object is attained, by an antenna feeding circuit, according to the present invention, in which micro-strips lines are constituted from one or more pair(s) of band conductors (5a, 5b) disposed on the outer surface of the cylindrical body (1) and an inner conductor (6) disposed on the whole of the inner surface of the cylindrical body (1). A 180 degree distributor (2) supplies electric power to the band conductors (5a, 5b) so that the phase difference between the currents in the band conductors (5a, 5b) is 180 degrees. Inutile current induced in the inner surface of the inner conductor can be cancelled out, because the inner conductor 6 is disposed on the whole of the inner surface of the cylindrical body (1).
