Antenna structure and the manufacturing method therefor

摘要

An antenna structure is provided. The antenna structure includes a radiating portion having an approximately quadrangular body, wherein the quadrangular body has a first side, a second side opposite to the first side, a third side, and a fourth side opposite to the third side; and a ground portion surrounding an entire length of the first side, an entire length of the fourth side, and at most a half of a length of the second side.

主权项

1. An antenna structure comprising:
a radiating portion having a quadrangular body, wherein the quadrangular body has a first side, a second side opposite to the first side, a third side, and a fourth side opposite to the third side; a feeding terminal adjacent to the first side; a first extending portion determining a central operating frequency of the antenna structure, and extending from the second side to form a first space between the first extending portion and the second side, wherein the first extending portion includes a connecting end and an open end, wherein the connecting end is connected to the second side, extends toward a first direction from the second side, forms a first bend, and then extends toward a second direction; and a second extending portion determining an operating bandwidth of the antenna structure, wherein the second extending portion extends from the third side, wherein a length of the first extending portion along the second direction is larger than a length of the second extending portion, the first extending portion has a width smaller than that of the second extending portion, the width of the first extending portion is smaller than a length of the second side, and the width of the second extending portion is smaller than a length of the third side.
