Description

A kind of Internet of Things antenna

Technical field

The utility model relates to antenna technical fields, more particularly to a kind of Internet of Things antenna.

Background technique

Technology of Internet of things is the inevitable choice of the trend of the following object and object networking, but at present due to Internet of Things base station Also be not it is very perfect, layout covering it is comprehensive not enough, can there is a situation where that signal is weak in many places, for example, high building inside, ground Lower parking lot etc. place.Traditional antenna is unipole antenna, or increases a lower margin on the route of unipole antenna, is become Dipole antenna, but the bandwidth of this two kinds of antennas is limited, signal transmitting is limited with received ability under some specific environment.

Utility model content

The purpose of this utility model is to provide a kind of Internet of Things antennas that signal can be improved and receive with emissivities.

A kind of Internet of Things antenna disclosed by the utility model the technical solution adopted is that: a kind of Internet of Things antenna, including base Plate and coaxial line, the upper surface of base plate are equipped with radiating surface, and the radiating surface includes the first radiation area.

The radiating surface further includes the second radiation area, and second radiation area is disposed in parallel in the one of first radiation area Side, second radiation area include the first broken line, the second broken line, third fold line, and second broken line is L-type, first folding Line is linear type and the hook part for being connected to second broken line, and the third fold line is also L-shaped, and the hook part of the third fold line connects The outside for connecing the vertical part of second broken line and first broken line being set in shape is surrounded, the hook part of the third fold line and institute The hook part for stating the second broken line is parallel, and the vertical part of the third fold line is parallel with the vertical part of second broken line, first broken line It is parallel with the vertical part of second broken line.

Preferably, first radiation area includes fourth fold line and the 5th broken line, the 5th broken line be it is U-shaped, It is arranged on the outside of the fourth fold line in shape is surrounded, the fourth fold line is also U-shaped, the fourth fold line and the 5th broken line Head, bottom it is parallel with tail portion difference.

It preferably, further include thering is feed point to be arranged between the fourth fold line and the head of the 5th broken line.

It preferably, further include the hook part for having feedback place that second broken line is set.

Preferably, the core of the coaxial line connects the feed point, and the ground of the coaxial line connects the feedback place.

Preferably, the feed point and feedback place are gold-plated.

The utility model provides a kind of Internet of Things antenna, on the basis of the first radiation area, is further added by one second radiation Area makes by the wiring of the second broken line of the L-type of the second radiation area, the third fold line of L-type and linear first broken line The frequency of two radiation areas reaches the frequency of the first radiation area, and the first radiation area and the second radiation area energy double frequency are coupled out one more The bandwidth widened, so as to improve the signal reception and emissivities of antenna.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the Internet of Things antenna of the utility model.

Specific embodiment

The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below: please referring to figure 1, a kind of Internet of Things antenna, including substrate 10 and coaxial line, 10 upper surface of substrate are equipped with radiating surface, and the radiating surface includes First radiation area 30.

The radiating surface further includes the second radiation area 20, and second radiation area 20 is disposed in parallel in first radiation area 30 side, second radiation area 20 include the first broken line 22, the second broken line 24, third fold line 26, second broken line 24 For L-type, first broken line 22 is linear type and the hook part for being connected to second broken line 24, and the third fold line 26 is also in L Type, the hook part of the third fold line 26 connect the vertical part of second broken line 24 and are arranged in shape is surrounded in first broken line 22 Outside, the hook part of the third fold line 26 is parallel with the hook part of second broken line 24, the vertical part of the third fold line 26 with The vertical part of second broken line 24 is parallel, and first broken line 22 is parallel with the vertical part of second broken line 24.

First radiation area 30 includes fourth fold line 32 and the 5th broken line 34, and it is in surround that the 5th broken line 34, which is U-shaped, In 32 outside of fourth fold line, the fourth fold line 32 is also U-shaped, the fourth fold line 32 and the 5th broken line for shape setting 34 head, bottom are parallel with tail portion difference.

It should be noted that further including the head for having feed point 40 that the fourth fold line 32 and the 5th broken line 34 is arranged in Between.It further include the hook part for having feedback place 50 that second broken line 24 is set.The core of the coaxial line connects the feed point 40, The ground of the coaxial line connects the feedback place 50.The feed point 40 and feedback place 50 are gold-plated, gold-plated effectively to improve feed point 40 and the inoxidizability in feedback place 50 can effectively improve feed point 40 and feedback ground simultaneously because the high conductivity of gilding The electric conductivity of point 50.

The frequency of the first radiation area 30 is set to reach 824 by the wiring of U-shaped fourth fold line 32 and the 5th U-shaped broken line 34 ~960M, log mag at this time only has -5.64~3.15dB, then passes through linear first broken line 22, the second broken line of L-type 24 and the wiring of third fold line 26 of L-type so that the frequency of the second radiation area 20 is reached 824~960M, in this way 824~960M just As soon as there is double frequency to be coupled out the broader antenna of a bandwidth, log mag at this time has reached -17.23~10.96dB, has brighter Aobvious promotion also increases the reception and emissivities of antenna accordingly

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
