1. An antenna module, comprising:
a first antenna layer, comprising at least one main radiation unit and at least one feeder portion, wherein the main radiation unit comprises at least two main radiation patches symmetrically arranged and spaced apart from each other, the feeder portion is disposed in or arranged corresponding to a gap between adjacent two of the main radiation patches, and the feeder portion is electrically connected or coupled to the main radiation patches;
a second antenna layer, stacked with the first antenna layer and comprising a reference ground and at least one microstrip, wherein the reference ground is arranged opposite to the main radiation patches, the microstrip is disposed on a layer where the reference ground is located, disposed between the reference ground and the main radiation patches or disposed on a side of the reference ground facing away from the main radiation patches, the microstrip is insulated from the reference ground, and a first end of the microstrip is configured to be electrically connected to a radio frequency (RF) transceiver chip;
at least one first conductive member, electrically connected to the main radiation patches and the reference ground; and
at least one second conductive member, wherein an end of the second conductive member is electrically connected to the feeder portion and another end of the second conductive member is electrically connected to a second end of the microstrip;
wherein the second antenna layer is defined with at least one hollow portion enclosed by the reference ground, and the microstrip is disposed in the hollow portion and spaced apart from the reference ground; and
wherein the microstrip comprises two end sections opposite to each other and a middle section connected between the two end sections, and a spacing between each of the end sections and the reference ground is greater than a spacing between the middle section and the reference ground.
