[0046] [First Embodiment]

[0047] First, see figure 1 and figure 2 , figure 1 Is a schematic top view of the antenna structure of the first embodiment of the present invention, that is, a schematic diagram of the antenna structure implemented on a substrate, figure 2 It is a schematic diagram of the circuit architecture of one implementation of the antenna structure of the first embodiment of the present invention. The present invention provides an antenna structure U, which includes a substrate 1, a first radiating element 2, a second radiating element 3, a first inductor 4, a grounding element 5, a first conductive element 6 and a feed-in Piece F. The first radiating element 2, the second radiating element 3, the first inductor 4, and the first conductive element 6 can be disposed on the substrate 1, and the first inductor 4 can be coupled to the first radiating element 2 and the second radiating element 3 In other words, one end (not numbered in the figure) of the first in...

[0054] [Second Embodiment]

[0055] First, see Figure 4 , Figure 4 It is a schematic diagram of the circuit architecture of one implementation of the antenna structure of the second embodiment of the present invention. by Figure 4 versus figure 2 It can be seen from the comparison between the second embodiment and the first embodiment that the antenna structure U provided by the second embodiment may further include a stub. Thereby, through the setting of the residual band 7, the center frequency of the third frequency band in the second operating frequency band can be adjusted.

[0056] In view of the above, further speaking, the remnant strip 7 can be disposed on the substrate 1 and formed integrally with the first conductive member 6 and the second radiating element 3. At the same time, the remnant strip 7 can have an open end 71 and a coupling The connecting end 72 of the first conductive member 6. According to the embodiment of the present invention, the connecting end 7...

[0059] [Third Embodiment]

[0060] First, see Figure 7 , Figure 7 It is a schematic diagram of the circuit architecture of one implementation of the antenna structure of the third embodiment of the present invention. by Figure 7 versus figure 2 It can be seen from the comparison that the third embodiment differs from the first embodiment in that the antenna structure U provided by the third embodiment may further include a parasitic element P, whereby the second parasitic element P can be added. The gain of the first frequency band range and the second frequency band range in the operating frequency band.

[0061] In view of the above, further speaking, the parasitic element P can be disposed on the substrate 1 and adjacent to the second radiation portion 32. In addition, one end of the parasitic element P can be coupled to the grounding element 5. In the third embodiment, the parasitic element P can have a first parasitic portion P1 coupled to the grounding element 5 and a fi...

Abstract

The invention discloses an antenna structure. The antenna structure comprises a substrate, a first radiation piece, a second radiation piece, a first inductor, a grounding piece, a first conductive piece and a feeding piece, wherein the first radiation piece is arranged on the substrate, the second radiation piece is arranged on the substrate and is provided with a feeding part, the first inductoris coupled between the first radiation piece and the second radiation piece, the first conductive piece is coupled between the feeding part and the grounding part, and the feeding piece is coupled between the feeding part and the grounding piece and is used for feeding a signal. A technical scheme that the inductor is coupled between the first radiation piece and the second radiation piece can beused for preventing mutual influence among different frequency bands.

Description

technical field [0001] The present invention relates to an antenna structure, in particular to an antenna structure with multiple operating frequency bands. Background technique [0002] First of all, with the increasing usage rate of portable electronic devices (such as smart phones, tablet computers, and notebook computers), the wireless communication technology of portable electronic devices has been paid more attention in recent years, and the quality of wireless communication depends on the quality of portable electronic devices. depends on the antenna efficiency. Therefore, how to increase the gain of the antenna has become very important. Furthermore, although some existing antenna architectures (such as planar inverted-F antenna (PIFA)) can generate multiple frequency bands, different frequency bands will affect each other, resulting in The matching effect of the antenna becomes poor. [0003] In addition, with the advent of the next-generation communication techn...
