Abstract

For AM/FM B.C. and cellular mobile telephone (MT) in vehicles, a tri-band antenna, which is commonly used for both AM/FM and MT, is desired to reduce the number of antennas on the body. In this paper, composition of the tri-band antenna is described, and the tri-band antenna with double sleeves which are used for the antenna instead of the coils is described.
