Router with external antenna

Abstract

This application discloses an external antenna for a router, including a housing. The housing contains a first cavity and a second cavity, located vertically and vertically respectively. A first antenna is housed in the first cavity, and a second antenna is housed in the second cavity. The first antenna is obliquely fixed to the inner wall of the first cavity, and the second antenna is perpendicular to the first antenna. The second antenna is fixedly connected to the inner wall of the second cavity via a bracket. This external antenna achieves dual polarization by adding horizontal polarization to the existing vertical polarization through the mutual oblique arrangement of the first and second antennas, thereby increasing the router's throughput and improving its performance.

Description

Technical Field

[0001] This application relates to the field of antennas, and in particular to an external antenna for a router. Background Technology

[0002] An external antenna is an antenna that connects to a wireless router or other wireless communication device to enhance the reception and transmission of wireless signals. It is typically attached as an add-on to the device's external port. Its primary purpose is to improve the device's wireless communication performance, especially in environments where increased signal coverage is needed or where signal coverage is limited.

[0003] Existing external antennas are not compatible with multiple frequency bands, resulting in poor router throughput. Utility Model Content

[0004] The purpose of this invention is to provide an external antenna for a router to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This application discloses an external antenna for a router, characterized in that: it includes a housing, and a first cavity and a second cavity are respectively provided in the upper and lower parts of the housing. A first antenna is provided in the first cavity, and a second antenna is provided in the second cavity. The first antenna is obliquely fixed on the inner wall of the first cavity, and the second antenna is arranged perpendicularly to the first antenna. The second antenna is fixedly connected to the inner wall of the second cavity through a bracket.

[0007] Preferably, in the above-mentioned external antenna for router, the first connecting line of the first antenna extends into the second cavity, and the bottom surface of the housing is provided with a through hole for the first connecting line of the first antenna and the second connecting line of the second antenna to pass through.

[0008] Preferably, in the above-mentioned external antenna for router, the bracket is provided with a plurality of guide slots for guiding the first connecting line from top to bottom, and the bracket below the plurality of guide slots is provided with a slot for fixing the first connecting line and the second connecting line.

[0009] Preferably, in the above-mentioned external antenna for routers, the bottom surface of the housing is detachably connected to the housing, and the bracket is integrally formed with the bottom surface of the housing.

[0010] Preferably, in the above-mentioned external antenna for routers, a threaded post is protruding from the bottom surface of the housing.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] By setting the first antenna and the second antenna to be inclined with respect to each other, horizontal polarization is added to the original vertical polarization, thereby achieving dual polarization, and thus increasing the throughput of the router and improving the performance of the router.

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments recorded in the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0014] Figure 1 The following shows a schematic structural diagram of an external antenna for a router in a specific embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will combine the drawings in the embodiments of the present invention to describe the technical solutions in the embodiments of the present invention in detail. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0016] Refer Figure 1 As shown, the external antenna for a router in this embodiment includes a housing 1. A first cavity 2 and a second cavity 3 are respectively provided above and below in the housing 1. A first antenna 4 is provided in the first cavity 1, and a second antenna 5 is provided in the second cavity 3. The first antenna 4 is fixedly inclined on the inner wall of the first cavity 1, and the second antenna 5 is arranged perpendicular to the first antenna 4. The second antenna 5 is fixedly connected to the inner wall of the second cavity 3 through a bracket 6.

[0017] Further, the first connection line 401 of the first antenna 4 extends into the second cavity 3, and a wire passing hole 7 for the first connection line 401 of the first antenna 4 and the second connection line 501 of the second antenna 5 to pass through is provided on the bottom surface of the housing 1.

[0018] Further, a plurality of guiding grooves 8 for guiding the first connection line 401 are sequentially provided on the bracket 6 from top to bottom, and a clamping groove 9 for fixing the first connection line 401 and the second connection line 501 is provided on the bracket 6 below the plurality of guiding grooves 8.

[0019] Further, the bottom surface of the housing 1 is detachably connected to the housing 1, and the bracket 6 is integrally formed with the bottom surface of the housing 1.

[0020] Further, a threaded column 10 protrudes from the bottom of the bottom surface of the housing 1.

[0021] In this technical solution, by tilting the first antenna and the second antenna relative to each other, horizontal polarization is added to the original vertical polarization, thereby achieving dual polarization, which increases the router's throughput and improves its performance.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0023] The above are merely specific embodiments of this application. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
