[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example 1: This embodiment discloses a three-dimensional orthogonal antenna array structure, such as Figure 1-2As shown, the array comprises three magnetic loop antennas 1 and three (electric) dipole antennas 2. The three magnetic loop antennas have the same diameter and are orthogonally arranged to form six intersections. Each magnetic loop antenna's two intersections are connected by a dipole antenna, and the three dipole antennas intersect at the vertical intersections of the three magnetic loop antennas. The dipole antennas' feed points are located at the intersections of the three dipole antennas. By integrating the three orthogonal magnetic loop antennas and the three orthogonal dipole antennas, a stable three-dimensional structure is formed, creating a six-channel three-dimensional orthogonal antenna. The following methods ensure reliable electrical connections between the individual antennas, mutual insulation between the six antennas, and a robust and reliable antenna array structure.

[0022] Each magnetic loop antenna consists of two opposing circular oscillators made of aluminum alloy plates of a certain width. Non-metallic material is clamped between the two oscillators using screws to maintain an insulation distance between them.

[0023] At the intersection of the magnetic loop antenna and the dipole antenna, in addition to ensuring electrical connection and insulation between the antennas, a cross-fixing system is also required to ensure the antennas are properly shaped and fixed. The design considers the dipole antenna as the main support, and the three magnetic loop antennas as the connecting parts of the dipole antenna to ensure overall stability.

[0024] A non-metallic box 3 with a square cross-section is installed at each of the six intersections. Slots are cut into the four sides of the box to secure two orthogonal magnetic loop antennas. The two oscillators of the dipole antenna described below are mounted on the other two opposing surfaces. The six boxes connect the magnetic loop antenna to the main support (dipole antenna) as a single unit.

[0025] The ring elements of the magnetic loop antenna are designed as irregular ring structures. Specifically, notches are provided at the intersection of each pair of magnetic loop antennas, and each notch is oriented in a different direction to avoid the intersection of the other pair of magnetic loop antennas. This ensures that the magnetic loop antenna elements are both insulated and do not interfere with each other when they intersect.

[0026] Each dipole antenna consists of two oscillators, which are located at both ends of the intersection of the three dipole antennas. To ensure insulation between the dipole antenna oscillators and the magnetic loop antenna, each oscillator is divided into two sections by the non-metallic box at the intersection. The two sections are connected by a thin aluminum plate and fixed with screws to ensure good and reliable electrical contact of the oscillators.

[0027] The oscillator of the dipole antenna is an aluminum alloy tube with low density and good conductivity.

[0028] A cube-shaped non-metallic box 4 is placed at the intersection of the three dipole antennas, with a vibrator fixed to each of its six faces via a non-metallic flange. A flange 5 is connected to a corner of the box via a non-metallic support rod 6, forming a fixed base for the antenna array structure.
