AM-FM-Cellular Mobile Telephone Tri Band Antenna for Vehicles 890122

ABSTRACT

Recently, mobile telephones have become very popular in many countries. At present, however, many users mount one antenna for the mobile telephone and another antenna for AM/FM B.C. bands on their cars, which tends distract from the beauty of the cars. Ordinary mobile telephone antennas are fixed-type and can be easily damaged. We often hear that cars with a mobile telephone antenna ore more likely to be stolen or broken-into.

To solve these problems, Fujitsu Ten has developed an AM-FM-Cellular mobile telephone tri band antenna. Users can shorten or extend this new antenna with its dedicated motor, and store the antenna inside the fender of the car when not in use. Like ordinary antennas, this new antenna is a rod with three connection points. When the antenna is fully extended, the users can use a radio and a mobile telephone at the same time. In addition, we have provided almost the same electrical performance as each single-purpose antenna.
