    • A high frequency filter for frequencies higher than the VHF band comprising of a closed conductive housing (53), a pair of input and/or output means (54) like an antenna provided at both the extreme ends (53-5, 53-6) of said housing (53), a plurality of resonators (51-1 through 51-5, and 51a-1 through 51a-5) arranged on a straight line between said antennas (54), each of said resonators having an elongated inner conductor (51a-1 through 51a-5) with a circular cross section, and an elongated rectangular dielectric body (51-1 through 51-5) surrounding said inner conductor, one end of each of said resonators being fixed at the single plane (53-1) of the housing (53) and the other end of each of said resonators being free standing. The length of said inner conductor and the dielectric body is substantially 1/4 wavelength, and the duration (52-1 through 52-4 ) between two resonators is determined according to the specified coupling coefficient for the desired characteristics of the filter. Due to the rectangular dielectric body (51-1 through 51-5), each resonator is stably mounted on the housing (53), and then, the stable characteristics of the filter is obtained. Thus, the use in a vibrated circumstance like a mobile communication is possible. That rectangular dielectric body (51-1 through 51-5) also provides the larger coupling coefficients between resonators, and then, the wideband filter can be obtained.
