Dipole antenna device, earphone antenna device, and wireless communication terminal device connected to the device
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.
