Integrated antenna and sensor element apparatus for a portable wireless terminal

摘要

An apparatus with a metal member used as at least one of an antenna and a sensor element in a portable terminal is disclosed. The apparatus includes the metal member, responsive to a sensed body, and for transmitting and receiving a signal in at least one or more communication service bands, and a main board having a communication module for processing a signal transmitted and received by the metal member and a sensor module for obtaining information in response to the approach of a sensed body.

主权项

1. A portable terminal comprising:
a patterned metal member used for both an antenna radiator for transmitting and receiving signals in one or more communication service bands, and as a sensor element that senses whether a sensed body is proximate the portable terminal; a circuit board comprising:
a communication module electrically coupled to the patterned metal member for processing a first signal received by the patterned metal member; anda sensor module electrically coupled to the pattern metal member and obtaining a second signal from the patterned metal member that differs in frequency from the first signal, and generating a signal based on the second signal which varies in response to the sensed body; and a case frame; wherein the patterned metal member includes an extension, the extension being a first portion of the patterned metal member which is extended beyond the circuit board to an external edge of the case frame and is arranged along the external edge so as to form a portion of an external appearance of the portable terminal, while a remaining portion of the patterned metal member is disposed on the circuit board inside the portable terminal.
