Technical Field

[0001] The utility model relates to the field of radio technology, in particular to a comprehensive matching short-wave antenna without an external ground grid. Background Art

[0002] In the prior art, the common structure of a shortwave antenna includes an inductor coil and a radiating element. The antenna usually needs to be connected to an external ground grid to ensure its communication efficiency and stability. The length and configuration of the external ground grid usually depend on the geographical location of the operation and the height of the human body from the ground, which makes the deployment and adjustment in different environments more complicated. Such antennas are widely used in portable communication equipment, such as amateur radio equipment and certain military communication equipment, where portability and rapid deployment capabilities are particularly important.

[0003] However, the requirement for an external ground grid for traditional portable shortwave antennas increases setup time and complexity, especially in mobile conditions or in changing terrain. Matching the appropriate ground grid length and configuration can be very challenging. Traditional antennas typically have low power tolerance, which limits their use in high-power applications, affecting the overall ease of use and transmission efficiency of the antenna, making it impossible for users to quickly or effectively deploy and use these devices in emergency or special situations.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 4The utility model provides a technical solution: a comprehensive matching shortwave antenna without external grounding grid, comprising: a coil skeleton 1, a top cover 2, an inductance coil 3, an antenna base 4 and a radiation vibrator 5, wherein a winding portion is arranged on the outer side of the outer wall of the coil skeleton 1, and a through hole is arranged at the central part of the coil skeleton 1; the top cover 2 is arranged at the top end of the coil skeleton 1; the inductance coil 3 is counterclockwise wound on the winding portion on the outer side of the outer wall of the coil skeleton 1 in a top-down arrangement; the antenna base 4 is arranged at the bottom end of the coil skeleton 1; the radiation vibrator 5 is detachably arranged at the top end of the top cover 2 and connected to the head end of the inductance coil 3, a matching jumper is arranged inside the coil skeleton 1, and the matching jumper is located at 1 / 4 of the total length of the inductance coil 3, a threaded column 6 is arranged at the bottom end of the radiation vibrator 5, and the radiation vibrator 5 is screwed to the middle part of the top cover 2 through the threaded column 6.

[0019] In the specific implementation, it should be noted that a through hole is provided in the center of the coil frame 1, and a winding portion is provided on the outer side of the outer wall thereof for the subsequent installation of the loading coil 3. The loading coil 3 is wound on the winding portion of the coil frame 1 from top to bottom in a counterclockwise direction, and this specific winding method helps to achieve the predetermined electrical performance. The radiating vibrator 5 can be quickly replaced or adjusted in different application scenarios to adapt to different communication needs. The entire installation process needs to ensure the precise alignment and firm connection of each component to ensure the overall performance and reliability of the antenna. The diameter of the low-band coil frame 1 is not less than 30 mm. The loading coil 3 is integrated with the matching coil. The wavelengths of different short-wave bands are different. The low-band frequency is low and the wavelength is longer. The length of the antenna is different due to different bands. Therefore, the loading coil 3 is shortened by the induction method. Different bands are wound counterclockwise upward on the frame according to the diameter of the coil frame 1. The loading rate of the loading coil 3 with different wire diameters and intervals is different, so the jumper matching at the golden position of 1 / 4 of the total coil length can achieve the best impedance and ground network matching effect and transmission efficiency.

[0020] In some examples, further, the radiating vibrator 5 is a retractable telescopic antenna, which is matched according to different bands by means of an internal jumper of the loading coil 3, and impedance matching is performed based on the housing volume of the QRP shortwave equipment on the market and the comprehensive conditions of the human body ground network. Radiating vibrators 5 of different lengths can be well matched by adjusting the length of the loading coil 3 and the position of the matching jumper.

[0021] In some examples, further, the length of the loading coil 3 matches the position of the matching jumper, the loading coil 3 and the matching coil are integrated, and the antenna base 4 and the coil frame 1 are integrated.

[0022] In some examples, further, the antenna base 4 is provided with a shielding layer 41 and a center layer 42, the shielding layer 41 of the antenna base 4 is connected to the end of the loading coil 3, and the center layer 42 of the antenna base 4 is connected to the loading coil 3 through a flying wire inside the loading coil 3.
