1. A device, comprising:
a substrate comprising a grounding area;
a clearance area adjacent to the grounding area; and
an antenna apparatus comprising:
a first radiating element disposed in the clearance area and comprising:
an opening comprising:
a first side; and
a second side;
a first ground terminal located on the first side and electrically coupled to the grounding area; and
a second ground terminal located on the second side and electrically coupled to the grounding area,
wherein the first radiating element and the grounding area jointly form a slot antenna;
a second radiating element disposed in the clearance area and separated from the grounding area;
a first feeding structure located at the clearance area, grounded, and configured to:
excite the slot antenna in a magnetic coupling manner to generate a first resonance frequency; and
excite the second radiating element to generate a second resonance frequency;
a third radiating element configured to excite the slot antenna in an electrical coupling manner to generate the second resonance frequency; and
a second feeding structure located at the clearance area and grounded,
wherein the second feeding structure is electrically coupled to the third radiating element and is configured to excite the third radiating element to generate the first resonance frequency,
wherein a first resonance mode of the slot antenna and a second resonance mode of the third radiating element are orthogonal in polarization at the first resonance frequency, and
wherein a third resonance mode of the second radiating element and a fourth resonance mode of the slot antenna are orthogonal in polarization at the second resonance frequency.
