Smart Antenna for Wireless Communications
First Claim
1. A smart antenna including a plurality of parasitic antenna elements provided with configuring devices, a voltage supply arranged to be coupled to the configuring devices and to supply a DC voltage, and a control unit operable to tune DC voltages applied to the configuring devices, wherein each parasitic antenna element can be reconfigured either as a reflector or a director on the basis of the voltage applied thereto, wherein the smart antenna includes a driven element which is a reconfigurable directional antenna including first, second and third inverted F-type antenna (IFA) elements angularly spaced from one another.

Abstract
A smart antenna includes a plurality of parasitic antenna elements provided with varactors, a voltage supply arranged to be coupled to the varactors and operable to supply a DC voltage, and a control unit operable to tune DC voltages applied to the varactors, wherein each parasitic antenna element can be reconfigured either as a reflector or a director on the basis of the voltage applied thereto. The driven element is surrounded by first and second 10 annular arrays of parasitic elements at radii of substantially 25 and 50 mm respectively, each annular array including six antenna elements. The array is configurable for steering the beam. The arrangement is compact and efficient.
