Claim 7:
8. A dual-band antenna module, comprising:
a first antenna structure including a first insulating substrate, a conductive metal layer, a plurality of grounding supports, and two first feeding pins; and
a second antenna structure including a second insulating substrate, a top metal layer, a bottom metal layer, a second feeding pin, two auxiliary conductive elements and two coupling metal layers;
wherein the conductive metal layer is disposed on a top side of the first insulating substrate, the grounding supports are configured to support the first insulating substrate and separate from the conductive metal layer, and the two first feeding pins are disposed on a bottom side of the first insulating substrate and separate from the conductive metal layer;
wherein the second insulating substrate is disposed above the first insulating substrate, the top metal layer is disposed on a top side of the second insulating substrate, the bottom metal layer is disposed on a bottom side of the second insulating substrate to contact the conductive metal layer, the two coupling metal layers are respectively disposed on two lateral sides of the second insulating substrate and are separate from the top metal layer and the bottom metal layer, each of the two auxiliary conductive elements penetrates through the first insulating substrate and is separate from the conductive metal layer, and the second feeding pin is disposed on the bottom side of the first insulating substrate and is electrically connected to the two coupling metal layer through the two auxiliary conductive elements, respectively;
wherein the first antenna structure is configured for transmitting or receiving a first frequency band signal, the second antenna structure is configured for transmitting or receiving a second frequency band signal, and the first frequency band signal that is transmitted or received by the first antenna structure is smaller than the second frequency band signal that is transmitted or received by the second antenna structure.
