INTEGRATED ANTENNA AND SENSOR ELEMENT APPARATUS FOR A PORTABLE WIRELESS TERMINAL

摘要

An apparatus interworking with a metal member used both as 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. An apparatus comprising:
an antenna adapted to obtain a first signal in a first frequency band, and a second signal in a second frequency band; a communication circuitry coupled with the antenna and adapted to communicate with a first object external to the apparatus using the first signal received from the antenna; a sensor circuitry coupled with the antenna and adapted to detect a second object external to the apparatus using the second signal received from the antenna; and a filter circuitry formed between the sensor circuitry and the antenna, and adapted to decouple the sensor circuitry with the antenna with respect to the first signal, or couple the sensor circuitry with the antenna with respect to the second signal.
