Description
Technical Field
[0001] The utility model relates to the technical field of antennas, and in particular to a novel rod-shaped 4G antenna. Background Art
[0002] Due to the characteristics of the antenna, antenna wavelength = speed of light / frequency, so the lower the frequency of the antenna, the longer the wavelength required. The antenna area required for a 4G antenna will be very large. When the required model is very small, how to make the antenna size smaller becomes a big problem.
[0003] The existing 4G rod antennas on the market are often large in size and are not suitable for small-sized products (due to aesthetic factors, etc.). In addition, traditional antennas are basically designed with PCB materials, which are large in size and expensive, and are not easy to change in direction for signal reception after installation. Utility Model Content
[0004] The utility model provides a novel rod-shaped 4G antenna, aiming to solve the problems that the traditional antenna is basically designed with PCB material, the PCB is large in size, high in price, and has poor receiving direction.
[0005] The utility model provides a novel rod-shaped 4G antenna, comprising a connector, a rotating seat, a spring as an antenna radiation vibrator, a rod sleeve, and a sleeve. The rotating seat is movably connected to the connector, the bottom of the spring is connected to the rotating seat, the top of the spring extends outward and then folds back, the sleeve is sleeved on the spring, the folded portion of the spring is separated from the intersection of the spring by the sleeve, and the rod sleeve is sleeved on the outside of the spring and connected to the rotating seat.

[0007] As a further improvement of the present invention, the spring is a carbon steel spring.
[0008] As a further improvement of the utility model, the sleeve is a plastic heat shrink sleeve.
[0009] As a further improvement of the present invention, the rotating seat is provided with a rotating groove, and one end of the connector is provided with a rotating column, and the rotating column is movably connected in the rotating groove.
[0010] As a further improvement of the utility model, a plurality of concave rings are arranged on the rod sleeve.
[0011] The beneficial effects of the utility model are as follows: the antenna structure achieves a smaller antenna size by changing the shape of the spring while meeting the antenna frequency band requirements; in addition, by adding a rotating seat at the bottom of the rod sleeve, when the rod sleeve needs to be rotated, the rotating seat only needs to be rotated around the connector to achieve a 360-degree rotation of the rod sleeve, which is convenient for changing the orientation to receive signals and has strong flexibility. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a structural diagram of the novel rod-shaped 4G antenna in the utility model;
[0013] Figure 2 It is a cross-sectional view of the connection position between the rotating seat and the connector in the utility model. DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] like Figure 1 to Figure 2 As shown, a new type of rod-shaped 4G antenna of the utility model comprises a connector 1, a rotating seat 2, a spring 3 as an antenna radiation vibrator, a rod sleeve 4, and a sleeve 5. The rotating seat 2 is movably connected to the connector 1, the bottom of the spring 3 is connected to the rotating seat 2, the top of the spring 3 extends outward and then folds back, the sleeve 5 is sleeved on the spring 3, the folded portion 7 of the spring 3 is separated from the intersection of the spring 3 by the sleeve 5, and the rod sleeve 4 is sleeved on the outside of the spring 3 and connected to the rotating seat 2. The spring 3 is a carbon steel spring 3. The sleeve 5 is a plastic heat shrink sleeve 5.
[0016] The bottom of the spring 3 is a straight rod structure, the middle of the spring 3 is a spirally wound coil 6, the top of the spring 3 is a folded straight rod structure, and the folded portion 7 at the top of the spring 3 is separated from the intersection of the coil 6 by a sleeve 5. Since the edge of the coil 6 is relatively close to the folded portion 7 at the top of the spring 3, in order to prevent short circuit, it is preferred to put a plastic heat shrink sleeve 5 at the position of the coil 6 to separate the two.
[0017] In this antenna structure, a carbon steel spring 3 is installed inside the rod sleeve 4, and a rotating seat 2 is installed at the bottom of the rod sleeve 4. The carbon steel spring 3 is connected to the rotating seat 2. The top of the spring 3 adopts a folded structure to increase antenna coupling, because 4G antennas have many frequency band requirements, and antenna coupling can increase the frequency band of the antenna. In addition, the carbon steel spring 3 can be wound into a coil 6 shape, and the folded intersection of the spring 3 is separated by a heat shrinkable plastic sleeve 5 to prevent short circuits, which greatly reduces the area required for the antenna, so that the antenna size can be made very small to meet the needs of customers for small-sized products. The rotating seat 2 is connected to the connector 1, and the antenna transmits and receives electromagnetic wave signals outward through the connector 1.
[0018] The rotating seat 2 is provided with a rotating groove 21, and a rotating column 11 is provided at one end of the connector 1, and the rotating column 11 is movably connected in the rotating groove 21. Through the matching connection between the rotating column 11 and the rotating groove 21, the rotating seat 2 can rotate 360 degrees relative to the connector 1, which is convenient for flexible change of direction to receive and transmit antenna signals.
[0019] A plurality of concave circles 8 are arranged on the rod sleeve 4. The plurality of concave circles 8 form a concave-convex feeling on the surface of the rod sleeve 4, which can play an anti-slip role and facilitate hand force application when rotating the rod sleeve 4.
[0020] The 4G rod-shaped antenna of the present invention is designed with a spring 3 made of carbon steel, which has the advantages of easy production, small size, and low price. In addition, by making the spring 3 into the required coil shape and isolating the intersecting parts with a heat shrink tube 5 to prevent short circuit, the antenna size is reduced and the antenna performance is guaranteed; in addition, by adding a rotating seat 2 at the bottom of the rod sleeve 4, when the rod sleeve 4 needs to be rotated, only the rotating seat 2 needs to be rotated to achieve a 360-degree rotation of the rod sleeve 4, which can facilitate changing the orientation for transmitting and receiving signals and has strong flexibility.
[0021] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
