Antenna and button assembly for wireless devices
First Claim
1. A wireless headset comprising:
- an elongated metal housing portion having a longitudinal axis;
a microphone mounted in the metal housing portion;
a circuit board;
a switch attached to the circuit board;
a button guide structure that contains a guide channel;
a reciprocating member that is guided in the guide channel, that operates the switch, and that reciprocates along the longitudinal axis of the elongated metal housing portion; and
an antenna resonating element that is formed around the button guide structure so that the antenna resonating element at least partially surrounds the reciprocating member and so that the antenna resonating element at least partially surrounds the longitudinal axis.

Abstract
An antenna and button assembly is provided for a compact portable wireless device such as a wireless headset for a handheld electronic device. An antenna structure is mounted within a button structure. The button structure includes a switch actuation member that extends past the antenna structure and into engagement with a switch. The switch actuation member may reciprocate within the button structure. A user may press upon an exposed end of the switch actuation member to operate the switch. The switch may be used to control the application of power to the compact portable wireless device or to perform other suitable functions. The button structure may be formed using dielectric materials such as plastic. By forming the button structure from dielectric, clearance is provided between the antenna structure and conductive portions of the compact portable wireless device so that the antenna of the compact wireless device operates properly.
