Abstract
An antenna arrangement includes an antenna reflector (10), a transceiver element (11) and a signal detection unit (12) having a signal converter (121-122) and a computing unit (123) for generating in response to incoming signals control signals for controlling the alignment of the antenna reflector (10) with a target object. The signal converter (121-122) is adapted to reduce its bandwidth automatically and incrementally from a requisite maximum frequency range to a narrow band frequency range. Changes in the direction of the antenna reflector are detected through the medium of a movement detection unit (13) that includes 3d-sensors (131, 132, 133). Mechanical control of the alignment direction of the antenna reflector (10) is effected with the aid of a drive unit (15).
Claims15
An antenna arrangement comprising:
- an antenna reflector;
- a transceiver element coupled to said antenna reflector;
- a signal detection unit and a movement detection unit attached to a rear side of said antenna reflector, said signal detection unit coupled to said transceiver element for processing signals incoming from a target and for generating, responsive to said incoming signals, a first control signal for controlling alignment of the antenna reflector with the target, said signal detection unit including a signal converter and a computing unit in series, said signal converter activating and maintaining a bandwidth at a maximum frequency range until a desired input signal is detected within said bandwidth and then reducing said bandwidth automatically and incrementally from said maximum frequency range to a narrowband frequency range so as to achieve a highest detectable sensitivity for said desired input signal;
- said movement detection unit having a signal output connected to a signal input of said computing unit and including a plurality of sensors having three-dimensional sensing capability, said movement detection unit detecting changes in the alignment of said antenna reflector through said three-dimensional sensors and generating a second control signal in response thereto;
- and
- a drive unit for controlling alignment of said antenna reflector in response to said first and second control signals.
