Antenna`s beam direction adjusting device for cellular mobile telephone system, has position detecting unit with magnetic rod to induce voltage into secondary coils, where movement of rod represents movement of dielectric unit

摘要

The device has an elongated box-like housing comprising upper and lower parts, and a feed line structure comprising feed line segments that are connected to a set of feed connection terminals. One of the terminals is connected to a transceiver circuit that is included in a base station. A position detecting unit has a magnetic material rod (504) for inducing voltage into a pair of secondary coils (502, 503). The movement of the rod represents a movement of the dielectric unit, where the dielectric unit is provided with a linear potentiometer. An independent claim is also included for an antenna control system comprising an array of antennas.
