Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a high-gain omnidirectional outdoor waterproof terminal antenna. Background Art

[0002] In the current communication field, common products on the market of omnidirectional external waterproof fiberglass antennas (3300-3800MHz) have many shortcomings. These antennas usually have conventional size designs, follow traditional process methods, and have relatively conventional internal structures. They are mostly constructed of copper tubes or copper tubes plus multi-section spring vibrators.

[0003] However, this structure has obvious defects. On the one hand, the antenna gain is low and it is difficult to meet the increasingly high communication quality requirements. On the other hand, due to its complex process and high production cost, it not only increases the production burden of enterprises, but also leads to low production efficiency. In a market environment with fierce competition and increasing requirements for communication performance, these conventional antenna products have been difficult to adapt to new demands and challenges. Utility Model Content

[0004] The utility model aims to provide a high-gain omnidirectional outdoor waterproof terminal antenna to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution, which includes a radio frequency connector, a radio frequency coaxial cable is welded on the radio frequency connector, a FR4 antenna vibrator is welded on the other end of the radio frequency coaxial cable, a phosphor bronze three-unit antenna vibrator is welded on the other end of the FR4 antenna vibrator, and the other end of the phosphor bronze three-unit antenna vibrator is sleeved with EVA foam.

[0006] As a preferred embodiment of the utility model, a metal aluminum sleeve is spirally provided on the RF connector, a fiberglass shell is provided on the metal aluminum sleeve, the fiberglass shell covers the outside of the RF coaxial cable, FR4 antenna element, phosphor bronze three-unit antenna element and EVA foam, and the EVA foam is fixed on the inner wall of the fiberglass shell.

[0007] As a preferred embodiment of the present invention, the top of the fiberglass shell is connected to a top cover by glue.

[0008] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0009] 1. The utility model effectively prevents moisture from invading the interior of the antenna through the fiberglass shell and related connection structures, so that it can still work stably in a humid or rainy environment, greatly expanding its application scenarios, and can operate reliably both outdoors and in harsh weather conditions.

[0010] 2. The utility model adopts FR4 plate and high-quality phosphor bronze copper wire as antenna radiation oscillators, as well as a unique multi-oscillator spring overall design, which significantly improves the gain of the antenna, enhances the ability to receive and send signals, and helps to achieve longer-distance and more stable communications.

[0011] 3. The overall process of the utility model is simple, and the production process is relatively simple. It does not require complicated processes and technologies, reduces the requirements for production equipment and technicians, is easy to mass produce, and the connection and assembly methods between the components are easy to operate, which reduces errors and rework in production and improves production efficiency. At the same time, simple processes and convenient operations help reduce the waste of raw materials, reduce labor costs and time costs, thereby reducing overall production costs.
