Embodiment

[0039] 1. An antenna structure with three operating frequency bands, comprising a radiating portion, wherein the radiating portion comprises a first branch conductor path, a second branch conductor path and a third branch conductor path. The second conductor branch path is electrically connected to the first conductor branch path; and the third conductor branch path includes a first extension portion additionally extended from the second conductor branch path. One of the second and the third conductor branch paths is a longest path among the first, the second and the third conductor branch paths; the longest path includes a shared area; and the second conductor branch path and the third conductor branch path share the shared area.

[0040] 2. The antenna structure according to embodiment 1, wherein: the radiating part further includes a feed end; a shared conductor branch path having the shared area is included between the second conductor branch path and the third conductor b...

Abstract

The invention relates to an antenna structure with three operating frequency bands and a manufacturing method thereof. The antenna structure comprises a radiation part which comprises a first conductor branch path, a second conductor branch path and a third conductor branch path, wherein the second conductor branch path is electrically connected to the first conductor branch path; the third conductor branch path comprises an extension part additionally extending from the second conductor branch path; one of the second and third conductor branch paths is the longest path in the first, second and third conductor branch paths; the longest path comprises a sharing region covering more than 1 / 3 of the longest path; the sharing region is shared by the second and third conductor branch paths.

Description

technical field [0001] The present invention relates to an antenna structure, and in particular to an antenna structure having multiple operating frequency bands. Background technique [0002] In today's era of rapid technological development, various sizes or types of lightweight antennas have been developed to be used in various sizes of increasingly lightweight handheld electronic devices (such as mobile phones or notebook computers), or wireless transmission device such as an access point, wireless network card, or wireless card bus. For example, a planar inverted F antenna (Planar Inverted F Antenna, PIFA) or a monopole antenna (Monopole Antenna) that has a light structure, good transmission performance, and can be easily installed on the inner wall of a handheld electronic device already exists and is widely used. It is widely used in wireless transmission devices of various handheld electronic devices or notebook computers or wireless communication devices. In the p...
