摘要： An earphone antenna device operable to be connected with a wireless communication terminal device includes: earphone cables, connected with earphone sections, respectively, for supplying audio signals; an audio cable one end of which is connected with the wireless communication terminal device and the other end is connected with the earphone cables; and a coaxial cable one end of which is connected with the wireless communication terminal device and the other end is connected with a pair of string-shaped antenna elements integrated with the earphone cables. The earphone cables are insulated from the antenna elements and the audio cable is insulated from the coaxial cable. This provides a dipole antenna device and an earphone antenna device hardly influenced by noises from the wireless communication terminal device and noises transmitted via the audio cable. Further, a wireless communication terminal device to be connected with the antenna devices is provided.

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.
