However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figures 1-4 As shown, this utility model provides a miniaturized PCB patch antenna, including two protective shells 1. Each of the two protective shells 1 has a mounting groove 2 on one side of its outer wall. The inner surface of each of the two mounting grooves 2 is fixed with a mounting bracket 3 by bolts. The inner surface of each of the two mounting brackets 3 is provided with a silicone moisture-absorbing plate 4 and a dustproof plate 5. A sealing ring 11 is provided on one side of the outer wall of one of the two protective shells 1, and a dustproof ring 12 is provided on one side of the outer wall of another of the two protective shells 1.

Furthermore, the sealing ring 11 and dustproof ring 12 effectively prevent dust and impurities from entering the interior of the protective shell 1, thus protecting the PCB patch antenna. Simultaneously, during the heat dissipation process of the PCB patch antenna, the silicone moisture-absorbing plate 4 and dustproof plate 5 filter and absorb dust and moisture in the air, preventing dust and moisture from entering the interior of the protective shell 1, thereby protecting the PCB patch antenna and preventing it from becoming unusable due to dust.
