Embodiment Construction

[0061]The present invention will be further described in detail with the help of the following preferred embodiments and accompanying drawings.

[0062] see figure 1 , which is a schematic diagram of the first embodiment of the three-dimensional dual-band antenna device of the present invention. Such as figure 1 As shown, the three-dimensional dual-frequency antenna device 1 of the present invention mainly includes three parts made of metal:

[0063] The grounding portion 11 presenting an L-shaped three-dimensional structure,

[0064] a high-frequency radiation part 12 corresponding to a high-frequency frequency range, and

[0065] The low-frequency radiation part 13 corresponding to the low-frequency frequency range and presenting an L-shaped three-dimensional structure,

[0066] Wherein, the high-frequency angle 121 between the high-frequency radiation part 12 and the grounding part 11 can be used to control the bandwidth of the high-frequency band, and the low-frequency...

Abstract

The invention relates to a three-dimensional dual-band antenna device comprising a Z-shaped antenna structure with a first bend and a second bend, wherein the first bend is connected with a grounding part and a first radiating part, and the second bend is connected with the first radiating part and a second radiating part with a first slotted hole. The first radiating part and the second radiating part are different in length. The three-dimensional dual-band antenna device also comprises a feedback part arranged at the second bend, an extension grounding part arranged at the outer side of thegrounding part in the manner of non-coplanar extension and an extension radiating part arranged at the outer side of the second radiating part in the manner of non-coplanar extension. The three-dimensional dual-band antenna device can effectively increase the work bandwidth and the output gain of the antenna and can effectively control the impedance matching of the antenna so that the antenna canachieve good voltage standing-wave ratio (VS-WR) output.

Description

technical field [0001] The invention relates to a three-dimensional antenna, in particular to a dual-frequency three-dimensional antenna. Background technique [0002] In today's era of rapid technological development, the size of handheld electronic devices (such as mobile phones or laptops) or wireless transmission devices (such as APs) is becoming smaller and smaller. developed. Selecting an appropriate antenna according to the type and demand of the product can not only help improve the transmission effect, but also further reduce the product cost. For example, the Planar Inverse-F Antenna (PIFA), which has a light structure, good transmission effect, and can be easily installed on the inner wall of a handheld electronic device, already exists and is widely used in various handheld electronic devices. During wireless transmission of electronic devices or wireless communication devices. The transmission method is to transmit the ground signal and the signal to be trans...
