Description

Technical Field

[0001] This utility model relates to the field of transmission antennas, specifically a 2.4GHz ISM band gooseneck antenna. Background Technology

[0002] 2.4GHz belongs to the ISM (Industrial, Scientific, and Medical Band), a frequency band primarily open to industrial, scientific, and medical institutions. The ISM band allows anyone to transmit data freely, but power is limited, restricting the distance between transmitters and receivers to a very short range, thus preventing interference between different users. Currently, many countries use the ISM band for wireless devices (especially home appliances), such as garage door openers, cordless phones, wireless mice, Bluetooth headsets, and wireless LANs. Most 2.4GHz antennas on the market are currently fixed-directional. This makes them inflexible when dealing with situations where the signal is strong in some directions and weak in others, resulting in poor compatibility and difficulty in adjustment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 2As shown, this embodiment of a 2.4GHz ISM band gooseneck antenna includes: a spring vibrator 1, an upper copper tube 2 and a lower copper tube 3 connected to each other, a coaxial line 4 passing through the lower copper tube 3, a gooseneck protection unit sleeved on the outside of the coaxial line 4, and an antenna cover 8 for covering the spring vibrator 1 and the copper tube unit. The spring vibrator 1 acts as an antenna during use to receive or transmit signals. The upper copper tube 2 is used to fix and connect the lower end of the spring vibrator 1 and the coaxial line 4, so that the spring vibrator 1 and the coaxial line 4 are electrically connected, thereby realizing the transmission of electrical signals between the spring vibrator 1 and the coaxial line 4. The gooseneck tube 5 is used to protect the coaxial line 4, and the antenna cover 8 is used to protect the spring vibrator 1, the upper copper tube 2, and the lower copper tube 3. The upper end of the upper copper tube 2 is connected to the spring vibrator 1, the lower end of the upper copper tube 2 is connected to the coaxial line 4, and the antenna cover 8 is detachably connected to the gooseneck protection unit. That is, only the lower end of the spring vibrator 1 is connected to the upper copper tube 2, so that the rest of the spring vibrator 1 is located outside the upper copper tube 2, which makes it easy to adjust the length of the top of the spring vibrator 1. Specifically, if the entire detection antenna is deflected to a lower frequency, the upper part of the spring vibrator 1 is shortened to shorten the vibrator length; if the detection antenna is deflected to a higher frequency, the upper part of the spring vibrator 1 is lengthened to lengthen the vibrator length.

[0021] Specifically, the spring vibrator 1 is riveted into the upper end of the upper copper tube 2, thereby improving the connection between the spring vibrator 1 and the upper copper tube 2 and preventing relative movement between the spring vibrator 1 and the upper copper tube 2.

[0022] Specifically, the coaxial cable 4 includes a braided section and a conductor section located at the end of the braided section, wherein the braided section serves as an outer conductor and the conductor section serves as an inner conductor. The conductor section is welded to the lower end of the upper copper tube 2, thereby connecting the conductor section of the coaxial cable 4 to the spring oscillator 1 through the upper copper tube 2.

[0023] Specifically, the braided part is welded to the inner wall of the lower copper tube 3, thereby fixing the coaxial line 4.

[0024] Specifically, the radome 8 is made of ABS material, which is ABS plastic. This gives the radome 8 advantages such as toughness, hardness and rigidity, providing better protection for the spring vibrator 1.

[0025] Specifically, the gooseneck protection unit includes a gooseneck tube 5 sleeved on the outside of the coaxial cable 4, metal parts 6 connected to both ends of the gooseneck tube 5, and a connector 7. The gooseneck tube 5 protects the outside of the coaxial cable 4, and the metal parts 6 can be connected to the lower copper tube 3, thereby making the coaxial cable 4 placed inside the gooseneck protection unit more stable.

[0026] Specifically, the two ends of the gooseneck tube 5 are respectively press-fitted with the metal part 6 and the connector 7. The metal part 6 is connected to the end of the lower copper tube 3 away from the upper copper tube 2, thereby facilitating the installation and disassembly of the gooseneck tube 5 with the metal part 6 and the connector.

[0027] Specifically, the outer wall of the metal part 6 is threadedly connected to the inner wall of the antenna cover 8. This allows the metal part 6 to drive the lower copper tube 3, which in turn drives the coaxial cable 4 and the spring vibrator 1 to connect with the antenna cover 8, achieving a more stable fixing effect. Preferably, thread-locking adhesive is applied between the threads to further enhance the fixing effect.

[0028] In this embodiment, during use, if the entire detection antenna deviates to a lower frequency, the upper part of the spring vibrator 1 is shortened to reduce the vibrator length; if the detection antenna deviates to a higher frequency, the upper part of the spring vibrator 1 is lengthened to increase the vibrator length, thereby flexibly adjusting the direction of the antenna.

[0029] The above structure achieves the fixation of the spring vibrator 1. By adjusting the length of the spring vibrator 1 located outside the upper copper tube 2, the antenna direction can be adjusted, thereby reducing the difficulty of antenna adjustment and improving compatibility with different situations. The entire structure has high electrical performance, convenient adjustment method, and can adjust the frequency band more flexibly.

[0030] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
