[0016] 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.

[0017] like Figures 1 to 3 As shown, a universal WIFI dual-band steel sheet antenna 1 structure of the utility model includes a steel sheet antenna 1 and a radio frequency line 2. The steel sheet antenna 1 includes an antenna bottom surface 3, an antenna support surface 4, an antenna main radiation surface 5, and an antenna feeding surface 6. The antenna bottom surface 3, the antenna support surface 4, the antenna main radiation surface 5, and the antenna feeding surface 6 are connected in sequence. The antenna bottom surface 3 is connected to the shielding layer 7 of the radio frequency line 2, and the antenna feeding surface 6 is connected to the core wire 8 of the radio frequency line 2. The antenna main radiation surface 5 is arranged in parallel with the antenna bottom surface 3 to couple out the antenna frequency.

[0018] The bottom surface 3 of the antenna is used to connect the shielding layer 7 of the radio frequency line 2, and is also the fixing surface of the antenna. The bottom surface 3 of the antenna is connected to the whole device by double-sided adhesive. The antenna feeding surface 6 is used to connect the core wire 8 of the radio frequency line 2, and in terms of spatial position, the antenna feeding surface 6 is spaced apart from the bottom surface 3 of the antenna. The main radiating surface 5 of the antenna is parallel to the bottom surface 3 of the antenna, and the required antenna frequency is produced by coupling between the two surfaces to adapt to the antenna frequency required by different machine environments, so as to solve the problem of different antennas being required for different machine environments. The antenna supporting surface 4 can serve as a supporting part between the main radiating surface 5 of the antenna and the bottom surface 3 of the antenna, and can also adjust the bandwidth and tilt of the antenna.

[0019] The steel sheet structure is formed by bending a single steel sheet at multiple locations to form the antenna bottom surface 3, the antenna support surface 4, the antenna main radiation surface 5, and the antenna feeding surface 6. Multiple surfaces are made of the same steel sheet, which can ensure that the materials of the multiple surfaces are consistent, making the antenna frequency more controllable and reducing costs.

[0020] The frequency of the antenna is adjusted by adjusting the length and width of the antenna main radiation surface 5 and the antenna bottom surface 3. The frequency is controlled by adjusting the length and width of the antenna main radiation surface 5 and the antenna bottom surface 3 in the steel sheet antenna 1. The smaller the length and width, the lower the frequency.

[0021] The distance between the main radiating surface 5 of the antenna and the bottom surface 3 of the antenna is adjusted to adjust the bandwidth of the antenna. The distance between the main radiating surface 5 of the antenna and the bottom surface 3 of the antenna constitutes the height of the antenna. By adjusting the height of the antenna, the bandwidth can be adjusted. Within 1 / 4 wavelength, the higher the height of the antenna, the larger the bandwidth.

[0022] The length of the antenna support surface 4 is adjusted to adjust the distance between the antenna main radiation surface 5 and the antenna bottom surface 3. The antenna main radiation surface 5 and the antenna bottom surface 3 are connected through the antenna support surface 4, so the length of the antenna support surface 4 directly determines the distance between the antenna main radiation surface 5 and the antenna bottom surface 3. The bandwidth of the antenna can be adjusted by adjusting the length of the antenna support surface 4.

[0023] The antenna support surface 4 is respectively connected vertically to the antenna main radiation surface 5 and the antenna bottom surface 3; or the antenna support surface 4 is respectively connected obliquely to the antenna main radiation surface 5 and the antenna bottom surface 3. By changing the inclination angle of the antenna support surface 4, the inclination of the antenna can be adjusted to adapt to the installation space inside different machines.

[0024] The general WIFI dual-band steel antenna structure also includes foam 9, which is arranged in the steel antenna 1, and the foam 9 is connected to the antenna main radiation surface 5 and the antenna bottom surface 3. The foam 9 plays a supporting role in maintaining the height of the antenna.

[0025] This product adopts the form of steel sheet structure + CABLE line. A relatively large steel sheet is used as the bottom surface 3 of the antenna, and a steel sheet parallel to the bottom surface is used as the main radiation surface 5 of the antenna. The coupling between the two surfaces of the steel sheet produces the required antenna frequency. The antenna bandwidth of this structure is relatively wide and is insensitive to environmental changes. The antenna with this structure can be directly applied to machines with space for installation, without matching and debugging according to the machine environment, solving the problem of using different antennas for different machine environments.

[0026] 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.
