[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0032] Reference Figure 1-7This is the first embodiment of the present invention, providing a miniaturized gate-type high-power electric field generator. This miniaturized gate-type high-power electric field generator includes a base 1 and a moving wheel 2. The moving wheel 2 is located at the bottom of the base 1. An adjustment assembly 3 and a load component 4 are provided on the top of the base 1. The adjustment assembly 3 includes a rotating component 31, a deflecting component 32, and a generator body 33. The rotating component 31 is connected to the generator body 33 via the deflecting component 32. The rotating component 31 includes a load slider 311. A rotating wheel 312 is mounted on one side of the load slider 311. A guide seat 313 is fixedly mounted on the side of the load slider 311 closest to the rotating wheel 312, and the guide seats 313 are distributed on both sides of the rotating wheel 312. The rotating wheel 312 is located away from the load slider 311. A turntable 314 is movably connected to one side of the turntable 314. An equipment bracket 315 is fixedly installed on the side of the turntable 314 away from the load slider 311. The equipment bracket 315 is connected to the rotating wheel 312 through the turntable 314, and the cross-section of the equipment bracket 315 is U-shaped. The rotating wheel 312 is divided into an inner ring and an outer ring. The inner ring of the rotating wheel 312 can rotate within the outer ring of the rotating wheel 312, and the outer ring of the rotating wheel 312 is fixed to the load slider 311. The guide seat 313 is fixed to both sides of the outer ring of the rotating wheel 312 by screws. The turntable 314 is fixedly connected to the inner ring of the rotating wheel 312, so that the equipment bracket 315 can rotate through the turntable 314 under the restriction of the outer ring of the rotating wheel 312, thereby completing the angle adjustment of the generator body 33.

[0033] The inner side of the guide seat 313 is provided with an arc-shaped guide groove 316, and the arc-shaped guide groove 316 is arc-shaped. The inner side of the turntable 314 is provided with equidistantly arranged rotary positioning holes 317, and the rotary positioning holes 317 are distributed in a ring array around the turntable 314. Screws are provided in the arc-shaped guide groove 316, and during use, the screws in the arc-shaped guide groove 316 are connected and fixed to the corresponding rotary positioning holes 317 in the turntable 314 to prevent the equipment support 315 from rotating.

[0034] A pad 318 is provided between the turntable 314 and the equipment support 315. The equipment support 315 is fixedly installed on the outside of the turntable 314 by the splicing plate 319. The pad 318 can avoid direct contact between the pad 318 and the equipment support 315, thereby reducing the resistance when the equipment support 315 rotates and ensuring the smooth operation of the device.

[0035] The deflector 32 includes a limiting seat 321, which is fixedly installed on both sides of the equipment bracket 315. The inner side of the limiting seat 321 is provided with a slot 322, and the inner side of the limiting seat 321 is also provided with equidistant limiting holes 323.

[0036] The generator body 33 includes a main body 331. A slot 322 is fixedly installed on the inner side of the limiting seat 321. The inner side of the main body 331 is provided with equidistantly arranged deflection positioning holes 333. The deflection positioning holes 333 are arranged in a ring array around the deflection shaft 332. The main body 331 is movably connected to the outside of the equipment bracket 315 through the deflection shaft 332. The main body 331 is snapped into the slot 322 through the deflection shaft 332, thereby being installed on the outside of the equipment bracket 315, so that the main body 331 can deflect on the equipment bracket 315 with the deflection shaft 332 as the center. Screws are provided in the limiting holes 323. During use, the screws in the limiting holes 323 are connected and fixed to the corresponding deflection positioning holes 333 in the main body 331 to prevent the main body 331 from rotating.

[0037] The polarization rotation angle of the rotating component 31 is ±360°, and the pitch adjustment range of the deflecting component 32 is ±45° when vertically polarized, and the horizontal adjustment range is ±45° when horizontally polarized. The device can adjust the different angles of the generator body 33 through the rotating component 31 and the deflecting component 32, thereby realizing the pitch adjustment and horizontal / vertical polarization adjustment of the device, which can be operated independently by one person.

[0038] The main body 331 is in the shape of a door frame and has a frequency range of 10 kHz to 100 MHz. The main body 331 can generate a strong electric field in the frequency range of 10 kHz to 100 MHz. Due to the compact door frame design, the size is greatly reduced, making it convenient for use in field testing or test vehicle scenarios.

[0039] The load component 4 includes a pulley assembly 41 and a column 42. The column 42 is fixedly installed on the top of the base 1. The load slider 311 is movably connected to the outside of the column 42 through the pulley assembly 41. The pulley assembly 41 can reduce the friction of the main body 331 on the surface of the column 42, making it easier to adjust the height of the device to meet different testing requirements.

[0040] The device, resembling a door frame and significantly reduced in size, is moved to a small darkroom or outdoor testing area for later use via the casters 2 on the base 1. When the device angle needs adjustment, the device bracket 315 is rotated, allowing it to rotate within the inner ring of the caster 312 via the connected turntable 314. This adjusts the rotation angle of the main body 331 outside the device bracket 315. The bracket is then fixed in place by screws in the arc-shaped guide groove 316 and corresponding rotation positioning holes 317 in the turntable 314, preventing the device bracket 315 from rotating further. The device's angle adjustment is simpler and more convenient. The process of changing the main body 331 from a horizontal state to a vertical state is a polarization adjustment. When it is necessary to change the pitch angle of the main body 331, the main body 331 is engaged with the slot 322 on the limit seat 321 through the deflection shaft 332. During rotation, the device is centered on the deflection shaft 332. After adjustment, the device is connected and fixed to the corresponding deflection positioning hole 333 in the main body 331 through the screw in the limit hole 323, preventing the main body 331 from rotating. This achieves the device's pitch adjustment and horizontal / vertical polarization adjustment, which can be operated independently by one person.

[0041] The time required for adjusting the device to different states is as follows:

[0042] a. Pitch angle adjustment in vertical polarization (00:00:06 ~ 00:00:47, 41s)

[0043] b. Rotate 360° perpendicular to the ground (00:00:47 ~ 00:01:27, 40s)

[0044] c. Polarization adjustment: Vertical → Horizontal (00:01:27 ~ 00:01:51, 24s)

[0045] d. Oscillates approximately ±15° under horizontal polarization (00:01:51 ~ 00:02:15, 24s)

[0046] e. Polarization adjustment: Horizontal → Vertical (00:02:15 ~ 00:02:34, 19s)

[0047] f. Altitude adjustment: Descent (00:02:34 ~ 00:03:29, 55s)

[0048] g. Altitude adjustment: Increase (00:03:29 ~ 00:03:58, 29s).

[0049] The generator body 331 is mainly composed of a parallel double-line structure, with the electric field primarily distributed between the parallel double lines. Its equivalent circuit diagram is shown below. Figure 6As shown, to achieve broadband impedance matching for the entire circuit, the characteristic impedance of the parallel twin lines must be matched with the load and also with the impedance of the signal source input port. In this design, the load is a high-power resistor with an impedance of XX Ohms; therefore, the characteristic impedance of the parallel twin lines should also be designed to be XX Ohms. For a uniform, lossless parallel twin transmission line, its characteristic impedance can be obtained through a functional relationship, where is the distance between the twin lines and is the diameter of a single transmission line. ε and μ are the permittivity and permeability of the medium surrounding the transmission line. By selecting appropriate transmission line structure parameters, the characteristic impedance of the parallel twin lines can be achieved to XX Ohms. At this point, the electromagnetic waves between the transmission lines are in a traveling wave state. Since the electric field generator needs to generate controllable high-intensity electric and magnetic fields in the frequency range of 10 kHz to 100 MHz, it has the capability to test large devices under test.
