摘要： An antenna of the present invention includes a coaxial cable, antenna elements (3a and 3b), and an unbalanced/balanced converter. The unbalanced/balanced converter has a high-pass circuit provided between an input terminal port1 and an output terminal port2 and a low-pass circuit provided between the input terminal port1 and an output terminal port3. Moreover, the high-pass circuit rejects frequencies within a VHF band, and the high-pass circuit and the low-pass circuit both pass frequencies within a UHF band. In response to a signal, inputted to the input terminal port1, which falls within the UHF band, the high-pass circuit and the low-pass circuit output signals that are inverted in phase and equal in amplitude with respect to each other. Therefore, the antenna has high transmission and reception sensitivity in a wide frequency range, i.e., in the VHF and UHF bands. This makes it possible to provide an antenna having high transmission and reception sensitivity in a wide frequency range.
