1. A chip-type antenna device, comprising:

  • a circuit board having a grounding portion;

    a packaged chip having an insulating body and at least one electronic component embedded in the insulating body, wherein the packaged chip has a plurality of grounding pads and a plurality of signal pads, the grounding pads and the signal pads are exposed from the insulating body and are electrically connected to the electronic component;

    a monopole coupling antenna, comprising;

    a grounding radiating metal disposed on the circuit board, wherein the grounding pads are connected to the grounding radiating metal; and

    a monopole radiating metal disposed on the insulating body of the packaged chip, the monopole radiating metal having a feeding point, wherein the monopole radiating metal is arranged apart from the electronic component and the grounding radiating metal;

    a grounding circuit disposed on the circuit board and connected to the grounding portion of the circuit board and the grounding radiating metal; and

    a feeding circuit electrically connected to the feeding point of the monopole radiating metal and one of the signal pads of the packaged chip;

    wherein the monopole radiating metal is configured to non-contact coupling with the grounding radiating metal and the electronic component when the packaged chip transmits a signal to the monopole radiating metal via the feeding circuit.
