Description

Technical Field

[0001] The present invention belongs to the technical field of ultra-low frequency to millimeter wave propagation, and in particular relates to an extremely wideband continuously controllable antenna system. Background Art

[0002] In modern communication applications, more and more frequency bands have been used, resulting in increasingly scarce spectrum resources. Therefore, spectrum resources have become an important goal for both the military and civilians. Especially since the electromagnetic spectrum has been put on the agenda, the detection and utilization of spectrum resources has become an important research topic. Especially driven by the demand for 6G, spectrum resources below 6GHz almost cover all the spectrum, making it difficult to serve other new communications and radar resources. In recent years, communication technology has developed towards millimeter wave and very low frequency bands, even extending to terahertz in high frequency bands and ultra-low frequency in low frequency bands. The coverage frequency of electromagnetic waves is getting wider and wider, so realizing spectrum perception within an extremely wide frequency range and controlling the spectrum resources in operation have become important means of effectively utilizing spectrum resources. It is also an important way to perceive and detect unknown signals, which can lay the foundation for communication and perception security.

[0003] The current frequency has covered ultra-low frequency to millimeter wave, and even terahertz frequency band, and the design of traditional sensing antenna is directly proportional to the wavelength of the working frequency. In the low frequency band, the wavelength of the antenna is very long, resulting in a large size of the antenna. In this frequency band, the wavelength of the antenna decreases with the increase of frequency, so the size of the antenna becomes an electrically small antenna or even a few tenths of the wavelength relative to the low frequency band. Therefore, it is difficult to achieve the integration and integrated design of the antenna with extremely wide coverage bandwidth, covering low frequency to high frequency.

[0004] However, ULF covers lower frequencies, and antennas can directly penetrate the ground, walls, and water, and can achieve hidden communications and detection, so the development of ULF is of great significance. However, traditional ULF antennas are difficult to miniaturize, and it is difficult to achieve integrated design and integration with microwave bands. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes an extremely wideband continuously control antenna system, which provides an extremely wideband antenna with an integrated design and multiple integration methods. It mainly adopts current excitation and voltage excitation to achieve control, and cooperates with the antenna structure to form an extremely wideband continuous control, which can meet the coverage of ultra-low frequency to millimeter wave bands, and the spectrum can be adjusted and controllable, realizing integrated communication from water to air and extremely wideband spectrum perception.

[0006] To achieve the above object, the present invention provides an extremely wideband continuously controllable antenna system, comprising:

[0007] An extremely wide voltage control system, a spherical electrode pair, and a rectangular ring electrode pair; wherein the extremely wide voltage control system is respectively connected to the spherical electrode pair and the rectangular ring electrode pair to provide voltage signals to the spherical electrode and the rectangular ring electrode respectively, and the straight line where the spherical electrode pair is located is parallel to the rectangular ring electrode pair;

[0008] A box is arranged below the rectangular ring electrode pair, wherein a saline solution is loaded inside the box, and the spherical electrode pair is arranged inside the saline solution and at both ends of the box;

[0016] Optionally, the radiation patch is a corrugated horn-shaped patch and is excited by a microwave signal.

[0017] Compared with the prior art, the present invention has the following advantages and technical effects:

A pair of spherical electrodes placed inside a saline solution is used to form a conductive fluid field to achieve low-frequency communication, and the working bandwidth and frequency of the current field can be adjusted by adjusting the pressure difference between the positive and negative electrodes of the spherical electrode. A rare earth-iron alloy material film is bonded to the top of the rectangular ring electrode, and the micro-displacement deformation generated by the rectangular ring electrode under voltage drive is used to make the film produce a corresponding frequency, and broadband low-frequency radiation is formed by the low-frequency radiation driven by the current field and the micro-displacement deformation of the rare earth-iron alloy film.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] refer to Figure 1 and Figure 2The present invention provides an extremely wideband continuous control antenna system, comprising: an extremely wide voltage control system 8, a spherical electrode pair 6 including a pair of positive and negative spherical electrodes, a piezoelectric film 4, a box of saline solution 7, a rectangular ring electrode pair including a pair of positive and negative rectangular ring electrodes, an alloy material film 2, and a radiation patch 1.

[0048] The rectangular ring electrode pair includes a negative rectangular ring electrode 5 and a positive rectangular ring electrode 3, the alloy material film 2 is a rare earth-iron alloy material film, the piezoelectric film 4 is a barium titanate film, and the radiation patch 1 is a corrugated horn-shaped patch.

[0049] The box loaded with saline solution 7, the negative rectangular ring electrode 5, the piezoelectric film 4, the positive rectangular ring electrode 3, the alloy material film 2 and the radiation patch 1 are bonded together in sequence from bottom to top; the radiation patch 1 is bonded to the alloy material film 2, the alloy material film 2 is bonded to the top of the positive rectangular ring electrode 3, the piezoelectric film 4 is arranged between the positive rectangular ring electrode 3 and the negative rectangular ring electrode 5, the negative rectangular ring electrode 5 is installed on the top of the box loaded with saline solution 7, the spherical electrode pair 6 is installed in the saline solution 7, the rectangular ring electrode pair and the spherical electrode pair both include a positive electrode and a negative electrode, and the electrode feeding end faces are coated with an electroplated silver film, which are respectively attached to the rectangular ring electrode pair and the spherical electrode pair 6.

[0050] The extremely wideband piezoelectric control system 1 is composed of a rheostat 81 and a filter 82. The voltage signal applied to the electrode is dynamically adjusted by adjusting the resistance value of the rheostat 81. The filter 82 ensures the stability and purity of the voltage signal, thereby ensuring the high-frequency and low-frequency radiation operations of the antenna system.

[0051] The spherical electrode pair 6 includes positive and negative spherical electrodes, both made of silver chloride, which are respectively connected to the positive and negative poles of the voltage source through an extremely wide voltage control system and placed inside the saline solution 7. By controlling the voltage loaded at both ends of the spherical electrode pair, a conductive fluid field is formed inside the saline solution 7 to achieve low-frequency band communication.

[0053] The spherical electrode pair 6 in the box loaded with saline solution 7 forms a conductive current field due to the conductive effect of salt water under the action of the pressure difference between the positive and negative electrodes of the spherical electrode.

Due to the conductive fluid field formed by the spherical electrode pair 6 in the saline solution 7, the system can also achieve effective communication in an underwater environment. At the same time, the coordinated work of the rectangular ring electrode pair and the alloy material film 2 ensures the communication capability in the air environment, and realizes the seamless connection between underwater and air communications.
