4g Waterproof Wand Antenna And Photovoltaic Enterprises Together To Change The Environment, Make The Sky More Blue Water Clear

Client Background:

A Fortune 500 holding company, a diversified high-tech and manufacturing company that is a manufacturer of inverters and energy storage systems.Demand:

Antenna with waterproof, anti-UV function, receiving signal distance 15M. Antenna size not more than 30 * 10MM.


Demand:

Antenna with waterproof, UV protection, while meeting the three major operators' signal reception.


Challenge:

The instability of operator signals in remote areas can produce signal interruptions, which tests the performance of the antenna, while the harsh environment of photovoltaics also presents some unique challenges, such as high and low-temperature undulations and vibrations, so to develop the right solution means breaking through technical and physical boundaries.


Solution: 

1.698-960MHZ/1710-2700MHZ full band coverage, larger size antenna can provide greater bandwidth and higher efficiency, affected by the size of the established equipment, according to the required antenna size to compress and tuning range, generally need a larger range of capacity changes to achieve frequency migration, so usually require multiple tuning elements and/or a wide range of tuning values, for which The engineer increases the amplification of the harmonic positive point of the antenna line, while re-matching the equipment circuit.

2. Size impact, engineers choose a high-quality copper rod and double-sided circuit board for debugging resonant frequency, dark room test up to 3DB gain and 60% efficiency.

3. Antenna and equipment connection to add 2MM thick waterproof silicone gasket double to ensure that the equipment and antenna internal structure is not affected by the rain.

4. UV agent is added to the plastic shell, no deformation and cracking after - 40 ˚C ~ + 80 ˚C high and low-temperature cycle test for 80H.

5. The overall size of the antenna after final assembly is 90*10MM, which is accepted by the customer after the actual test.


Economic benefits::

The customer has successfully brought the product to market and has achieved sales of 300,000 units.
