Characteristics and model selection of 3G built-in antenna

Features of 3G built-in antenna

I

High gain relativity, perfect processing technology, good consistency of goods delivery, built-in in machinery and equipment, beautiful and generous, without independent three prevention, which is greatly endangered by the surrounding environment. Generally, it must be customized by integrating the goods themselves

2、 3G built-in antenna model selection

The shape of 3G built-in antenna can be divided into: FPC / PCB / spring / ceramic / hardware spring / laser immediate forming technology (LDS).

At this stage, PCB antenna is generally selected. Under the condition of high cost management and general performance regulations, the spring LDS antenna is selected. The general 3G built-in antenna is endangered by the environment, and the design scheme or matching resistance must be customized.

FPC antenna: with excellent performance price ratio, it can adapt to a variety of shape colors after oil pump; The product has good flexibility, which can perfectly meet the standard arc surface; Perfect and stable processing technology, fast production cycle and good mass delivery;

It is applicable to the antenna design scheme of broadband intelligent products with high performance.

PCB antenna: the big difference between FPC antenna and FPC antenna is that FPC wireless antenna has very good flexibility, and PCB antenna is a hard board.

In terms of structure and installation, if it is necessary to bend its curved surface, choose FPC antenna. If it is a plan view, choose PCB antenna, which is easier to install than FPC.

Spring antenna: its major feature is low price, but low gain and band width. When it is built into the commodity, the antenna pairing must be adjusted.

Ceramic patch antenna: it occupies little indoor space and has good performance; The band width of ceramic patch wireless antenna makes it difficult to ensure multiple frequency bands;

Reasonably improve the integration degree of computer motherboard and reduce the limit of antenna on ID; The design scheme must be improved at the beginning of the definition of computer motherboard.

LDS antenna: the wireless antenna with unique shape surface is used, which can flexibly use the indoor space of the antenna;

In view of the physical requirements that the performance of the wireless antenna is closer to the natural environment, there are unique material regulations for the shell or support frame attached to the antenna, the processing technology is perfect, and there is a certain unqualified rate in the whole process according to the paint color.

Hardware Spring antenna: with high cost performance and reasonable cost control; The commodity has high compressive strength and is not easy to be damaged.

The processing technology is perfect and stable, the production cycle is fast, and the hardware spring sheet wireless antenna has good mass delivery. It has certain limitations in the application of antenna area and arc shape surface.
