Case analysis: Cowin 4G waterproof rod antenna changes the environment together with photovoltaic enterprises to make the sky bluer and the water clearer.
Customer Background:
World top 500 holding company, is a diversified high-tech and manufacturing enterprise of inverter and energy storage system manufacturers.
Business requirements:
The antenna is waterproof and uv resistant, and can receive signals from the three operators.
The challenge:
Unstable signals of operators in remote areas will cause signal interruption, which will test the performance of the antenna. Meanwhile, the harsh environment of PV also brings some unique challenges, such as fluctuation of high and low temperature and vibration. Therefore, to develop the right solution means breaking through the technical and physical boundaries.
Solution:
1.698-960mhz / 1710-2700mhz full band coverage, larger size of the antenna can provide greater bandwidth and higher efficiency, affected by the size of the finalized equipment, according to the required antenna size to compression and tuning range, generally need a larger range of capacity changes to achieve frequency migration, Therefore, multiple tuning elements and/or a wide range of tuning values are usually required, for which the engineer amplifies the harmonic points of the antenna line and re-matches the equipment circuit.
2. Due to size impact, engineers select high-quality copper rod and double-sided circuit board to debug resonant frequency, darkroom test up to 3DB gain and 60% efficiency.
3. Add a 2MM thick waterproof silicone gasket at the connection between the antenna and the equipment to ensure that the equipment and the internal structure of the antenna are not affected by rainy days.
4. The plastic shell is formed by adding UV agent, which is tested by -40 ˚C ~ + 80 ˚C high and low temperature cycle for 80H without abnormal deformation and cracking.
5. After the final antenna combination, the overall size is 90*10MM long, which is qualified by the customer's actual measurement and acceptance.
Economic benefits:
The customer has successfully introduced the product to the market, and 300,000 units have been sold.
