Antenna structure having a feed element formed on an opposite surface of a substrate from a ground portion and a radiating element
First Claim
1. An antenna comprising:
- a substrate having a first surface and a second surface;
a ground portion disposed on the first surface and having a recessed portion embedded in the ground portion at a depth to form an opening of an edge of the ground portion, wherein the recessed portion is opposite the opening of the edge of the ground portion, and the recessed portion is wider than the opening of the edge of the ground portion;
a radiating element disposed on the first surface, electrically connected to the ground portion, and defining a through hole, the radiating element comprising;
a first radiating trace including a first segment, a second segment and a first bended portion connecting the first segment and the second segment; and
a second radiating trace connected to the second segment; and
a feed element disposed on the second surface and electrically connected to the radiating element via the through hole of the radiating element on the substrate, wherein a projection of the feed element on the first surface partially overlaps the recessed portion.

Abstract
An antenna includes a substrate, a ground element, a radiating element and a feed element. The ground element is disposed on the substrate and has an opening. The radiating element is disposed on the substrate and electrically connects to the ground element. The radiating element comprises a first radiating trace and a second radiating trace. The first radiating trace includes a first segment, a second segment, and a first bended portion connected the first segment and the second segment. The second radiating trace connects to the second segment of the first radiating trace. The feed element is disposed on the substrate and electrically connects to the radiating element. The feed element and the radiating element are at the same surface of the substrate, and a part of the feed element extends and enters the opening.
