Dielectric intelligent 3G antenna
For the 3G base station antenna, 3G antenna miniaturization has no comparative advantage: not only can decrease the mechanical load, convenient installation of the 3G antenna, and can save precious days capital, for the 3G antenna system is a multi station supply more convenient conditions, in addition, also ten points to the 3G antenna and landscaping hidden works. Although the dual polarized smart antenna 3G scale is now than intelligent 3G antenna scale start to reduce by half the mercy, but also can not be called a miniaturized 3G antenna, small scale intelligent 3G antenna is still in developing and applying intelligent antenna 3G the future direction of expansion.
Because of the electromagnetic wave propagation characteristics of different in different medium, medium existence will affect the communication of the electromagnetic wave, using this feature, selection of high frequency low loss medium as filling materials, contact the 3G antenna structure properly, in the selection of the appropriate shape, dielectric constant and feeding method, can be used as a dielectric resonator the use of 3G antenna. One of the major advantages of the 3G antenna is that the size of the 3G antenna can be reduced greatly without changing the function of the 3G antenna.
Dielectric smart 3G antenna is the medium 3G antenna and smart 3G antenna to contact the manufacture of a few small smart 3G antenna. 3G TD-SCDMA smart antenna system is the use of 3G antenna array composed of multiple 3G antenna unit, using medium data can not only reduces single 3G antenna unit scale, but also can reduce the distance between the 3G antenna element, and then reduce the smart antenna for 3G entire scale. Miniaturization of the medium smart 3G antenna not only reduces the 3G antenna scale, together with the cost, ease of practical engineering equipment, the impact on the environment is reduced, there is a strong practical operability.
Along with the modern information science and electronic information science skills with penetration and full swing, appear intelligent 3G antenna and intelligent active medium 3G antenna system, the intelligent 3G antenna TD-SCDMA system end of miniaturization, integration, high performance and low cost etc. maybe. The smart antenna of the 3G medium long time interference TD-SCDMA system of "decent" questions are solved, the active 3G antenna of the integrated system of further progress, "tumor" questions can be smoothly done or easily solved plus optical fiber remote, skill has solved the "pigtail" questions, three questions long time TD-SCDMA system can get confused to solve. Miniaturization and integration not only makes the system more competitive in function, pricing, and other aspects of the use, because miniaturization also reduces the visual pollution, low radiation plus system, TD-SCDMA system will become the true meaning of green environmental protection system, TD-SCDMA system will also have more vitality. The expansion of the TD-SCDMA test network not only brings opportunities to the Chinese communications industry, but also greatly promotes the advancement of the skills of the China Mobile.
