MOBILE TELEPHONE ANTENNA DEVICE

摘要

PROBLEM TO BE SOLVED: To solve various problems about a trunk pole antenna and a printed glass antenna. SOLUTION: A mobile telephone antenna device 11 has an integral structure composed of a telephone antenna 12 and a radio transmitter/receiver 13. The telephone antenna 12 is equipped with a transmission/reception antenna element 15 whose feed point 25 is directly connected to the telephone RF input/output point 26 of the radio transmitter/receiver 13, and a receive-only antenna element 17 whose feed point 27 is directly connected to the telephone RF input point 28 of the radio transmitter/receiver 13. A feeder connected between the telephone antenna 12 and the radio transmitter/receiver 13 can be dispensed with, so that various problems caused by the feeder can be solved when a trunk pole antenna and a printed glass antenna are used.
