Patent ID: 7336236

Claim:
A triangular dipole antenna, comprising: a first substrate having a first surface and a second surface opposite to the first surface, wherein the first surface has a first feeding point and the second surface has a first grounding; a first radiating part, which is triangular and disposed on the first surface of the first substrate, wherein the first radiating part has a first interior angle electrically connected to the first feeding point; a second radiating part, which is triangular and disposed on the second surface of the first substrate, wherein the second radiating part has a second interior angle electrically connected to the first grounding; a second substrate disposed opposite to the first substrate and having a third surface and a fourth surface opposite to the third surface, wherein the third surface has a second feeding point and the fourth surface has a second grounding; a third radiating part, which is triangular and disposed on the third surface of the second substrate, wherein the third radiating part has a third interior angle electrically connected to the second feeding point; and a first via passing through the first substrate and the second substrate, wherein the first radiating part is electrically connected with the third radiating part by the first via.
