A handheld electronic device may be provided that contains a conductive housing and other conductive elements. The conductive elements may form an antenna ground plane. One or more antennas for the handheld electronic device may be formed from the ground plane and one or more associated antenna resonating elements. Transceiver circuitry may be connected to the resonating elements by transmission lines such as coaxial cables. Ferrules may be crimped to the coaxial cables. A bracket with extending members may be crimped over the ferrules to ground the coaxial cables to the housing and other conductive elements in the ground plane. The ground plane may contain an antenna slot. A dock connector and flex circuit may overlap the slot in a way that does not affect the resonant frequency of the slot. Electrical components may be isolated from the antenna using isolation elements such as inductors and resistors.

An accessory system (202, 402, 502) for a portable radio transceiver (200) includes an accessory device (206) which includes a speaker and/or a microphone disposed external of the portable radio transceiver. A cable (204) containing two or more conductors is provided for operatively connecting the accessory device to the portable radio transceiver. At least one antenna (210, 212) for the portable radio transceiver is integrated within the cable. When the accessory system is used with a multi-band portable radio transceiver, two or more antennas can be included in the cable, each optimized for operation on a particular RF frequency band.

There is provided a relay unit disposed between a mobile terminal that is a sound source and an earphone for outputting sound. The relay unit preferably wirelessly transmits/receives audio data to/from the mobile terminal and preferably transmits an operation signal to the mobile terminal.A headset is attached to the relay unit. The headset can be used as a wireless headset through Bluetooth communication with the mobile terminal. On the other hand, when the mobile terminal receives a digital mobile broadcast, the relay unit is connected to the mobile terminal via a shielded cable that also operates as a broadcast receiving antenna. Furthermore, while the relay unit is connected to the mobile terminal via a cable, a circuit driving battery included in the relay unit is charged.
