Abstract
Description
A broadband signal transmitting combined antenna device ranging from 0.02 GHz to 6 GHz Technical Field
[0001] This utility model relates to the field of antenna technology, specifically to a broadband signal transmission combined antenna device ranging from 0.02 GHz to 6 GHz. Background Technology
[0002] As is well known, with the development of the low-altitude economy, wireless devices such as drones, unmanned vehicles, walkie-talkies, and mobile communication equipment are widely used in cities. In specific situations (such as secure and confidential areas), electromagnetic shielding environments need to be constructed, giving rise to the demand for portable high-power communication jamming equipment. A single omnidirectional antenna cannot achieve ultra-wideband signal transmission from 0.02GHz to 6GHz; multiple antenna arrays are required to cover the entire frequency band. When the antenna spacing is less than half the wavelength of the operating frequency band, near-field electromagnetic coupling intensifies, leading to mutual interference of radiated fields. The parallel arrangement with the same polarization (to meet the omnidirectional radiation requirement) further amplifies the mutual coupling effect; power supply network mismatch causes signal reflection, and the reflected waves increase system noise through the mutual coupling channels. The large number of antennas, their dispersed installation, and complex structure, along with mutual coupling leading to deterioration of antenna standing waves and reduced transmission power efficiency, necessitate solutions to this technical problem. Summary of the Invention
[0003] (a) Technical problems to be solved
[0004] In view of the shortcomings of the existing technology, this utility model provides a broadband signal transmission combined antenna device of 0.02GHz to 6GHz.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a 0.02GHz to 6GHz broadband signal transmitting combined antenna device, comprising a transmitting mounting panel and nine omnidirectional antennas mounted thereon, wherein antennas 1 to 9 correspond to nine independent frequency bands: antenna 1: 0.02GHz to 0.4GHz, antenna 2: 0.1GHz to 0.2GHz, antenna 3: 0.4GHz to 0.52GHz, antenna 4: 0.7GHz to 1GHz, antenna 5: 1.8GHz to 2.2GHz, antenna 6: 2.3GHz to 3.6GHz, antenna 7: 4.8GHz to 5.3GHz, and antenna 8: 5.7GHz. The antenna ranges from 0.5GHz to 6GHz. Each antenna is fixed to the transmitter mounting panel via an N-type RF connector to achieve a common ground design. The arrangement and spacing of the antennas are as follows: from left to right, antennas 4, 6, 2, 1, 3, 5, 7, 9, and 8. The spacing between antennas 4 and 6 is 5cm, between antennas 6 and 2 is 10cm, between antennas 2 and 1 is 15cm, between antennas 1 and 3 is 15cm, between antennas 3 and 5 is 10cm, between antennas 5 and 7 is 5cm, between antennas 7 and 9 is 5cm, and between antennas 9 and 8 is 5cm.
[0007] Furthermore, the present invention is improved in that the N-type RF connector includes a female connector fixed on the transmitter mounting panel and a male connector located at the bottom of the antenna, and the antenna is directly mounted on the transmitter mounting panel by plugging in the male and female connectors.
[0008] Furthermore, the present invention is improved in that antennas 1 to 9 are all omnidirectional antennas.
[0009] (III) Beneficial Effects
[0010] Compared with the prior art, this utility model provides a broadband signal transmitting antenna device ranging from 0.02 GHz to 6 GHz, which has the following advantages:
[0011] This 0.02GHz to 6GHz broadband signal transmission antenna combination device spaces antennas with similar frequencies by more than 15cm to reduce near-field electromagnetic coupling, staggers the positions of high-frequency and low-frequency antennas to avoid octave band interference, and optimizes the antenna array to reduce the standing wave ratio and mutual coupling strength. Mutual coupling suppression directly reduces radiated energy loss and improves transmission power. The common ground design of the transmission mounting panel ensures consistent grounding across the entire frequency band and avoids reflection noise caused by power supply network mismatch. All antennas are directly fixed to the panel through standardized N-type connectors. The integrated design replaces the traditional scattered layout, reducing installation steps.

[0017] 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.
[0018] Please refer to Figures 1-4. This utility model is a broadband signal transmitting antenna device ranging from 0.02GHz to 6GHz, comprising a transmitting mounting panel and nine omnidirectional antennas mounted thereon. Antennas 1 to 9 correspond to nine independent frequency bands: Antenna 1: 0.02GHz to 0.4GHz, Antenna 2: 0.1GHz to 0.2GHz, Antenna 3: 0.4GHz to 0.52GHz, Antenna 4: 0.7GHz to 1GHz, Antenna 5: 1.8GHz to 2.2GHz, Antenna 6: 2.3GHz to 3.6GHz, Antenna 7: 4.8GHz to 5.3GHz, and Antenna 8: 5.7GHz to 5.6GHz. 9GHz, Antenna 9: 0.5GHz~6GHz, each antenna is fixed to the transmitter mounting panel via N-type RF connectors to achieve a common ground design. The arrangement and spacing of each antenna are as follows: from left to right, antenna 4, antenna 6, antenna 2, antenna 1, antenna 3, antenna 5, antenna 7, antenna 9, antenna 8. The spacing between antenna 4 and antenna 6 is 5cm, the spacing between antenna 6 and antenna 2 is 10cm, the spacing between antenna 2 and antenna 1 is 15cm, the spacing between antenna 1 and antenna 3 is 15cm, the spacing between antenna 3 and antenna 5 is 10cm, the spacing between antenna 5 and antenna 7 is 5cm, the spacing between antenna 7 and antenna 9 is 5cm, and the spacing between antenna 9 and antenna 8 is 5cm.
[0019] To facilitate antenna installation, in this solution, the N-type RF connector includes a female connector fixed on the transmitting mounting panel and a male connector located at the bottom of the antenna. The antenna is directly installed on the transmitting mounting panel by plugging in the male and female connectors, realizing direct plug-and-play installation of the antenna and the panel, simplifying the assembly process. Through the mechanical coupling of the male and female connectors, a common ground is ensured across the entire frequency band, eliminating signal reflection caused by ground potential difference.
[0020] To meet the omnidirectional radiation requirement, antennas 1 to 9 in this scheme are all omnidirectional antennas, ensuring omnidirectional radiation coverage without dead zones for interference signals. They maintain vertical polarization characteristics in a compact layout, avoiding performance loss caused by orthogonal arrangement. Each of the nine antennas is optimized for a specific sub-frequency band, and their combination achieves broadband coverage.
[0021] This invention discloses a 0.02GHz–6GHz broadband signal transmitting antenna combination device. During operation, it features low-frequency isolation: the low-frequency antennas block near-field magnetic field coupling; high-frequency compactness: the high-frequency antennas 7 (4.8–5.3GHz), 8 (5.7–5.9GHz), and 9 (0.5–6GHz) are spaced 5cm apart (approximately λ / 2≈2.5cm), utilizing the directional misalignment of the radiation field to suppress induced current; and a transition gradient: the intermediate-frequency antennas 4 (0.7–1GHz), 5 (1.8–2.2GHz), and 6 (2.3–3.6GHz) are spaced 10cm apart, balancing space occupancy and mutual coupling suppression. Spacing antennas with similar frequencies (such as antennas 1, 2, and 3) by more than 15cm weakens near-field electromagnetic coupling; staggering the positions of high-frequency and low-frequency antennas avoids octave band interference; and the optimized antenna array has a lower VSWR and weaker mutual coupling, resulting in increased transmission power.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
