摘要： The present invention is concerning an element antenna to construct an efficient antenna system, which is able to control mechanical movement of micro-strip patch antenna and to control electrical phase of signal. The movement of an element antenna is come from movement of a platform on which the element antenna is formed. The platform is made of dielectric material and able to move independently from base. The element antenna can be controlled to any direction. An antenna patch has magnetic material layer such as nickel on the backside. The antenna patch is driven by magnetic force.

摘要： The present invention relates to a beam steering system. The system includes an array of a plurality of antenna elements, each antenna element being electrically and mechanically controlled for steering a beam in a specific direction, and a millimeter wave subsystem quasi-optically integrated with a 3-dimensional beam steering device and an MMIC-type active circuit. The antenna element is controlled in real time by an electrical driving method so as to be moved in 2-dimensional space. That is, in the 3-dimensional system of the present invention, the beam is electrically controlled by a phase shifter, and each antenna element is physically moved by a mechanical driving mechanism. The 3-dimensional beam steering antenna and the associated devices are monolithically integrated on a substrate using MEMS technology, and the active circuit elements such as a mixer, a power amplifier (PA), a low noise amplifier (LNA), a VCO, etc. are integrated in an MMIC active array. The 3-dimensional beam steering device and the active MMIC circuit are integrated into one system by being interconnected using the quasi-optical technique. According to the present invention, shortcomings of the millimeter wave in that the SNR is low due to the low device output and high transmission loss in the free space can be overcome using the new RF transmission technique of 3-dimensional beam steering, and by introducing a micro antenna structure which is electrically and mechanically controlled such that wideband RF communication and 3-dimensional imaging is allowed in a Pico cell environment.
