Title: Device of diversity having directivity in wireless digital assistant
Inventor: CHO YOUNG CHANG
IPC: H04B7/08
Filed: 2002-01-31
Abstract: PURPOSE: A directional diversity device for a portable wireless terminal is provided to perform directional diversity by one antenna by changing the directivity of a directional antenna and receiving a signal with a different path. CONSTITUTION: The first and second conductors(121,122) change directivity. The directivity of a directional antenna(110) is changed according to a connection state of the first and second conductors(121,122) and the ground. The directional antenna(110) receives a wireless signal through a path of a corresponding direction, and transmits the wireless signal to a duplexer(130). A signal splitter(190) splits a receiving signal outputted from an IF(Intermediate Frequency) amplifier(180). A level detection and path selector(210) detects a level of the signal obtained in the signal splitter(190), and generates the first and second path selection signals for selecting the path of the receiving signal, according to the detected level. The first and second switches(123,124) perform switching operations according to the first and second path selection signals outputted from the level detection and path selector(210), and selectively connect the first and second conductors(121,122) to the directional antenna(110) so that the directivity is changed.
