DUAL-BAND ANTENNA DISPOSED ON BOTH SIDES OF A SUBSTRATE

摘要

A dual-band antenna disposed on the both sides of a substrate, including: a substrate, a first radiator and a second radiator. The substrate includes a first surface and a second surface; a feeding point is disposed at the edge of the first surface which may have a penetration hole electrically connected the first surface to the second surface. The first radiator extends from the first direction of the feeding point to the edge of the substrate, bend at the first corner, continues to extend toward the edge of the substrate, bends again at the second corner and then extend toward the third corner along the edge of the substrate. The second radiator straightly extends toward the second direction of the feeding point and the second direction's projection on the first surface is vertical to the first direction.

1. A dual-band antenna disposed on both sides of a substrate, comprising:
a substrate, formed with a first surface and a second surface in a manner that there is a feeding point disposed at a first edge of the first surface while the feeding point is further formed with a penetration hole to be used for electrically connecting the first surface to the second surface; a first radiator, arranged extending in a first direction from the feeding point along the first edge of the substrate, and then to be bended at a first corner so as to continue the extension along a second edge of the substrate, and then to be bended again at a second corner where it is further extending toward a third corner along a third edge of the substrate; and a second radiator, arranged on the second surface for allowing the same to extend in a straight line from the feeding point in a second direction while enabling the projection of the second direction on the first surface to be perpendicular to the first direction, i.e. the second radiator is arranged extending from the feeding point to the portion of the first radiator that is disposed neighboring to the third edge, and the projection of the second radiator does not overlap the first radiator.
