Antenna structure

Abstract

An antenna structure includes: a feed radiator, a ground radiator, a first radiator, a second radiator, and a carrier element. The feed radiator has a feed point. The ground radiator has a ground point. The first radiator is coupled to the ground radiator. The second radiator is coupled to the ground radiator, wherein the ground radiator, the first radiator, and the second radiator can collectively define a notch region. The feed radiator, the ground radiator, the first radiator, and the second radiator are all disposed on the carrier element, wherein the feed radiator is located within the notch region and can be at least partially surrounded by the ground radiator, the first radiator, and the second radiator.

Claims

1. An antenna structure, comprising: A feed radiator has a feed point; A grounded radiating part has a grounding point; A first radiating part is coupled to the grounded radiating part; A second radiating portion coupled to the grounding radiating portion, wherein the grounding radiating portion, the first radiating portion, and the second radiating portion together define a gap region; and a carrier element, wherein the feed radiating portion, the grounding radiating portion, the first radiating portion, and the second radiating portion are all disposed on the carrier element; wherein the feed radiating portion is located within the gap region and is at least partially surrounded by the grounding radiating portion, the first radiating portion, and the second radiating portion.

2. The antenna structure as described in claim 1, wherein the first radiating portion includes a first segment, a second segment, a third segment, and a fourth segment, the first segment and the second segment having a first included angle, the second segment and the third segment having a second included angle, and the third segment and the fourth segment having a third included angle.

3. The antenna structure as described in claim 2, wherein each of the first included angle, the second included angle, and the third included angle is an obtuse included angle.
