Antenna module and terminal thereof

An antenna module, comprising:

• an antenna array configured with a plurality of antenna units and a radio-frequency phase shifting system, wherein the antenna array and the radio-frequency phase shifting system are integrated on a circuit substrate to form an independent module;
• wherein:
• the radio-frequency phase shifting system comprises a millimeter-wave transceiver chip and a related circuit;
• the millimeter-wave transceiver chip and the related circuit are located on a face of the circuit substrate;
• the antenna unit of the antenna array is located on an opposite face of the circuit substrate
• the circuit substrate is a multilayer circuit substrate successively including a radiation patch layer, a first reference ground layer, a signal layer, a power layer, and a second reference ground layer, with each of the layers being stacked and spaced by dielectric substrates;
• the radiation patch layer and the first reference ground layer are electrically connected by a vertically extending antenna short-circuit pillar, with a feeder line as an input and output feed point, so as to form an antenna unit;
• a signal pin of the millimeter-wave transceiver chip is electrically connected to the feeder line by a chip signal connecting pillar via the signal layer;
• and
• a power pin of the millimeter-wave transceiver chip is electrically connected to the power layer by a power connecting pillar.
