Abstract

The invention provides a loop antenna array. The loop antenna array comprises a metal outer frame, a plurality of amplitude-phase control circuits, a control circuit, a frequency conversion transceiving circuit, a plurality of power combination circuits, a plurality of energy storage material pieces and a metal top plate, wherein the metal outer frame is provided with an annular columnar accommodating cavity; each power combination circuit comprises a power combination circuit composed of a passive antenna, a power amplifier and a low-noise amplifier circuit, a metal installation part used forinstalling the power combination circuit, and a radio frequency connector arranged on the bottom side of the power combination circuit. The metal top plate is horizontally arranged at the top of theaccommodating cavity and is fixedly connected with the metal outer frame, and a plurality of first windows and a plurality of second windows are formed in the metal top plate; the power combination circuit is arranged in the first windows in a penetrating mode, and the metal installation part is fixedly connected with the metal top plate. The energy storage material pieces are inserted into the second window, and the two ends of the energy storage material pieces make contact with the metal top plate and the amplitude-phase control circuits located on the uppermost layer respectively. The structure is compact and facilitates miniaturization.
