摘要： In order to provide a reflector antenna apparatus which can be installed within a small space, which has adequate practicality, and which can perform scanning by pivoting about two axes which are perpendicular to each other, in a reflector antenna apparatus having a Cassegrain reflector and a rotating mechanism which rotates the reflector about an azimuth axis and an elevation axis, a reflector with a substantially rectangular aperture has its elevation axis passing through substantially the central portion of the height dimension of the reflector, and reflector surface adjustment is carried out such that substantially all of the electromagnetic waves which are supplied are received and reflected, whereby the antenna height does not become large when the reflector rotates about the elevation axis. The reflector may be an array of a plurality of reflector elements.

摘要： A drive mechanism for an antenna array mounted on a moving vehicle. The antenna array is mounted on a disc having two motors which, cooperatively, rotate the disc and rotate a number of antenna elements mounted on the disc. By rotating the antenna elements, the main lobe of the array may be scanned towards a satellite in the elevation plane. To track a moving source from a moving vehicle, one of the motors rotates the disc as a whole, thereby scanning the beam in the azimuth plane. Each antenna element is at an angle to the vertical so that, by rotating the disc to face the direction of the signal source, such as a satellite, a better signal can be obtained.

摘要： The invention relates to a method for improving smart antenna array coverage. Arbitrary beam forming of an antenna array can be implemented by adjusting n antenna units beam forming parameter W(n), based on difference of size and shape between coverage required in engineering design and actually realized coverage. The method includes: setting an accuracy of W(n), i.e. an adjusting step length, setting a set of initial values W0(n), an initial value of mean-square error &egr;0, setting counting variable, setting threshold of ending adjustment M and maximum emission power of an antenna unit T(n). With the settings, a loop for W(n) adjustment is executed. A step-by-step approximation method is deployed for adjusting antenna radiation parameters, based on the minimum mean-square error criterion. Finally, an actual coverage of an antenna array approximates to the required coverage, under local optimization condition.

摘要： 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).
