Abstract
A mobile subscriber unit includes a smart antenna having antenna elements for generating a plurality of antenna beams, and adjustable weight control components connected to the antenna elements for selecting any one of the antenna beam. A transceiver is connected to the smart antenna. A beam selector controller is connected to the transceiver and operates in a coarse adjustment mode by jointly adjusting the weight control components when scanning through the antenna beams, and operates in a fine adjustment mode by independently adjusting the weight control components when one of the scanned antenna beams is selected.
Claims18
A mobile subscriber unit comprising:
- a smart antenna comprising
- a plurality of antenna elements for generating a plurality of antenna beams, and
- a plurality of adjustable weight control components connected to said plurality of antenna elements for selecting one of the plurality of antenna beams;
- a transceiver connected to said smart antenna;
- and
- a beam selector controller connected to said transceiver and operating
- in a coarse adjustment mode by jointly adjusting said plurality of weight control components when scanning through the plurality of antenna beams, and
- in a fine adjustment mode by independently adjusting said plurality of weight control components when one of the scanned antenna beams is selected.
