[0024] Please refer to Figures 1-3 The magnetic monitoring antenna 100 provided by the embodiment of the utility model includes a base 1, a signal processing part 2 and a signal radiator 3. The base 1 has a magnetic attraction structure 11, the magnetic attraction structure 11 is arranged at the bottom of the base 1, and includes a plurality of permanent magnets 12 arranged in a ring array to form a ring magnetic field region, the permanent magnets 12 are used for magnetic attraction installation on a magnetic surface, the signal processing part 2 is arranged at the top of the base 1, and the signal processing part 2 is used for processing antenna signals. The signal radiator 3 is installed on the upper part of the signal processing part 2, and the signal radiator 3 is used for transmitting or receiving antenna signals.

[0025] It should be noted that, considering that there are many electronic devices in the vehicle environment, in order to prevent the magnetic field generated by the magnetic attraction structure 11 from interfering with the active feed network 21 of the antenna itself and other electronic devices of the vehicle, a high-permeability magnetic shielding material can be used to wrap the permanent magnet 12 inside the base 1. This shielding material can effectively limit the magnetic field generated by the permanent magnet 12 to the area between the bottom of the base 1 and the metal surface of the roof, reducing magnetic field leakage. At the same time, a magnetic shielding layer can also be provided at the connection between the base 1 and the signal radiator 3 to prevent the magnetic field from adversely affecting signal transmission and ensure that the receiving performance of the antenna is not disturbed.

[0026] In an embodiment provided in the present application, the signal processing part 2 includes an active feed network 21, which is fixedly arranged on the upper surface of the base 1 and used for matching or amplifying the antenna signal.

[0027] In addition, the signal processing part 2 also includes a filter for filtering signal noise in the circuit.

[0028] In the present application, the signal radiator 3 is a single-sided structure radiator, and the signal radiator 3 is made of a thin straight metal pipe. The signal radiator 3 is used to transmit or receive antenna signals.

[0029] In the present application, the magnetic attraction type monitoring antenna 100 includes a shell 4 arranged outside the signal processing part 2. The shell 4 is provided with a plurality of sockets 41, including power sockets and coaxial sockets. The sockets 41 are electrically connected with the signal processing part 2.

[0030] In specific implementation: when the magnetic attraction type monitoring antenna 100 is used in a vehicle, the roof surface can be cleaned first, such as removing dust, oil stains and other debris, to ensure that the metal surface of the roof is flat and dry. Then, the base 1 containing the active feed network 21 and the magnetic attraction structure 11 is placed on the predetermined mounting position on the roof. At this time, the permanent magnets 12 evenly distributed at the bottom of the base 1 begin to work, and are attracted to the roof by the magnetic field generated thereby. If the thickness of the metal surface of the roof differs from the preset standard, or if the expected driving conditions are complex, the magnetic attraction strength needs to be further adjusted to ensure that the base 1 is firmly attached to the roof. Then, the threaded structure at the lower end of the single-sided structure radiator is aligned with the threaded interface at the upper end of the base 1 and is tightened to ensure firm connection. After the connection is completed, one end of the coaxial feeder is inserted into the coaxial socket on the side of the base 1, and the other end is connected to the short-wave signal receiving equipment inside the vehicle, such as a vehicle-mounted short-wave receiver. Finally, the power plug is inserted into the power socket on the side of the base 1 and connected to the power system inside the vehicle to provide stable power supply for the antenna.

[0031] It can be known from the structure and specific implementation process of the magnetic monitoring antenna 100 that the magnetic monitoring antenna 100 has wide adaptability and can be flexibly applied in multiple modes. The unique magnetic base 1 design enables the antenna to be easily switched between the vehicle-mounted antenna mode and the portable antenna mode. In the vehicle-mounted mode, the antenna is quickly and stably adsorbed on the roof through the magnetic structure 11, meeting the vehicle-mounted communication demand. In the portable mode, the antenna can be conveniently disassembled and carried, and deployed anytime and anywhere, greatly improving the scene adaptability of the antenna. The magnetic structure 11 in the circular metal structure base 1 is carefully designed. By reasonably arranging the permanent magnets 12 and adopting the magnetic shielding measures, the magnetic structure 11 not only has strong adsorption force and can resist various external forces in the vehicle driving to ensure that the antenna is closely attached to the roof, but also can effectively avoid magnetic field interference, ensuring the stable and reliable operation of the antenna in different use modes. The single-sided structure radiator and the double-port active feed matching network work cooperatively, improving the performance of the antenna from the signal receiving and processing level. Whether in the vehicle-mounted driving or the portable use scene, the antenna can accurately and stably receive the short wave signal, providing reliable data support for subsequent signal analysis and application.

[0032] In the description of the above-described embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0033] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
