[0055] First, see Figure 4 , Figure 4 It is a schematic circuit diagram of one implementation of the antenna structure of the second embodiment of the present invention. Depend on Figure 4 and figure 2 Comparison shows that the difference between the second embodiment and the first embodiment is that the antenna structure U provided by the second embodiment may further include a stub 7 (stub). Thereby, by setting the residual band 7, the center frequency of the third frequency band range in the second operating frequency band can be adjusted.

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

[0060] First, see Figure 7 , Figure 7 It is a schematic diagram of the circuit structure of one implementation of the antenna structure of the third embodiment of the present invention. Depend on Figure 7 and figure 2 The comparison shows that the difference between the third embodiment and the first embodiment is that: the antenna structure U provided by the third embodiment can further include a parasitic element P, whereby, through the setting of the parasitic element P, the second Gains of the first frequency band range and the second frequency band range in the operating frequency band.

[0061] Based on 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 ground element 5. In the third embodiment, the parasitic element P can have a first parasitic portion P1 coupled to the ground element 5 and a bend from the f...

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...
