[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a foldable patch antenna, comprising a first panel 1, a second panel on one side of the first panel 1, a patch 2 on one side of the second panel, connecting blocks 3 at the four corners of the opposite surfaces of the first and second panels, and a folding film 5 fixedly connected between the opposite surfaces of the first and second panels. The first and second panels are made of FR-4 epoxy glass cloth substrate, possessing good insulation and mechanical properties. The patch 2 is made of copper foil, exhibiting excellent conductivity. The folding film 5 is made of polyimide film, offering good flexibility and high-temperature resistance. This structure, through the cooperation of the first panel 1, the second panel, and the folding film 5, provides a foldable basic structure for the antenna, realizing its folding function and improving the convenience of transportation and storage. The horizontal plane of the folding film 5 is wavy, and antenna modules 6 are provided on each folded surface of the folding film 5. The antenna 6 uses a ceramic dielectric antenna, model AN-5800, with a wide operating frequency band. The wavy folded membrane 5 increases the effective radiation area of ​​the antenna. Combined with the antenna module 6, it expands the frequency band coverage of the antenna, improves the antenna's communication performance, and realizes multi-band communication function. A winding groove 10 is opened on the outer wall of the second panel, and a wire 4 is wound in the winding groove 10. Multiple limiting holes 9 are arranged in a rectangle on one side of the second panel. One end of the wire 4 is equipped with a wire connector, which is snapped into one of the limiting holes 9. The wire 4 is made of silver-plated copper wire with good conductivity. The winding groove 10 is made of ABS plastic, which is wear-resistant and not easily deformed. The winding groove 10 facilitates the storage of the wire 4, and the limiting holes 9 play a positioning role for the wire connector, avoiding wire clutter and improving the neatness and ease of operation when using the antenna.

[0020] In this invention, multiple docking blocks corresponding to connecting blocks 3 are provided on the opposite surfaces of the second panel and the first panel 1. A locking block 12 is fixedly connected to the opposite surface of the docking block and the connecting block 3. A rectangular plate is fixedly connected to the lower end of the locking block 12 on the docking block. The connecting block 3, docking block, locking block 12, and rectangular plate are all made of PA66 nylon, which is high in strength and wear-resistant. The locking block 12 and rectangular plate facilitate precise docking and clamping of the connecting block 3 and the docking block, improving the structural stability of the antenna after deployment. Mounting plates 7 are provided on one side of the opposite surfaces of the first panel 1 and the second panel. The two ends of the folded membrane 5 are respectively installed in the two mounting plates 7, and bolts 8 are passed through one side of each mounting plate 7. The mounting plates 7 are made of aluminum alloy. Made of gold, it is lightweight and high-strength; the bolts 8 are made of 304 stainless steel, which has good rust resistance; the cooperation between the mounting plate 7 and the bolts 8 realizes the stable installation of the folding membrane 5, while facilitating the disassembly and replacement of the folding membrane 5, thus improving the convenience of maintenance; the opposite surfaces of the connecting block 3 and the docking block are provided with corresponding rectangular plate and locking block 12 shaped slots, and the top surface of the connecting block 3 is movably provided between the inner top surface of the slot end; the pressing block 11 is made of silicone, which has good elasticity and comfortable operation; the cooperation between the slots, locking block 12, and rectangular plate, combined with the setting of the pressing block 11, realizes the quick locking and unlocking of the connecting block 3 and the docking block, improving the efficiency of antenna deployment and folding, and facilitating rapid deployment.

[0021] Working principle: When using this utility model, pressing the pressing block 11 releases the locking state between the connecting block 3 and the docking block, unfolding the first panel 1 and the second panel to the required angle, causing the folded film 5 to unfold in a wave shape. At this time, the antenna module 6 on the folded film 5 and the patch 2 on the second panel together form a complete antenna radiation structure. Pulling out the wire 4 from the winding groove 10 removes the wire connector that was originally stuck in the limiting hole 9 for positioning. Connecting it to the communication equipment as needed achieves circuit connection and meets the multi-band communication requirements; during signal transmission, external electromagnetic wave signals are absorbed by the patch 2 and the antenna module 6. The line module 6 receives signals, converts them into electrical signals, and transmits them to the communication device via the wire 4. Conversely, the electrical signals emitted by the communication device are transmitted to the patch 2 and the antenna module 6 via the wire 4, and then radiated out in the form of electromagnetic waves. When it is necessary to store the antenna, first disconnect the wire connector from the communication device, wind the wire 4 back into the winding groove 10, and then snap the wire connector back into the limiting hole 9 for positioning. Then press the pressing block 11 to separate the connecting block 3 from the docking block, fold the first panel 1 and the second panel towards each other, and the folding film 5 shrinks accordingly, reducing the overall size of the antenna for easy transportation and storage. At this point, the device is ready for use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
