PATTERN ANTENA TO IMPROVE SPEECH QUALITY FOR FOLDER TYPE MOBILE PHONE

摘要

PURPOSE: A pattern antenna is provided to prevent deterioration of communication quality even when the whip antenna is not extended, by allowing communication to be performed by using both whip and pattern antennas or selectively using the better path between the two antennas. CONSTITUTION: A pattern antenna comprises a pattern antenna(34) attached to the top of a portable phone; a whip antenna(35) attached to the bottom of the portable phone; a power combiner(33) for combining the waves sensed by the pattern antenna and the whip antenna; a matching unit(32) for inputting/outputting signals of the pattern antenna and the whip antenna through the power combiner, and improving gains of the pattern antenna and the whip antenna; and a duplexer(31) for inputting/outputting signals to the matching unit.
