4G antenna can be a low-cost, low-power and short-range wireless communication skills, can be widely used in any mobile communication equipment.

With the formal formulation of the 1.0 version of the 4G antenna standard in 1999, a short-distance wireless communication Network innovation seems to have been opened, and the wireless Personal Area Network (PAN) developed by the 4G antenna concept has been formally established.

So far, because the 4G antenna products launched on the market are not completely spread, the familiar term "4G antenna" is still giving people a feeling of "still holding the lute and half covering the face" in the use of products. Explore the reasons why its products have not been fully launched in addition to the 4G antenna standard has not been completely determined (2.0 version is under development); The other major factor is that the price of all 4G antenna modules remains high, which makes the price of 4G antenna products high. Ericsson's 4G antenna headphones, for example, are estimated to be around $200. Therefore, the quotation of the dropping module has become the direction of 4G antenna chip suppliers and peripheral component manufacturers.

"4G antenna" is the main essential component used to transmit and receive electromagnetic wave energy in wireless communication system. Because the current skills are not able to combine the 4G antenna into the chip of the semiconductor process, in addition to the central system chip in the 4G antenna module, the 4G antenna is another key component that affects the transmission characteristics of the 4G antenna module. In a variety of different 4G antenna products, the 4G antenna planning method used is not the same as the production of raw materials. In addition to helping to match the appearance of the product and improve the transmission characteristics of the 4G antenna module, the selection of the appropriate 4G antenna module can further reduce the cost of all 4G antenna modules. This is provided to 4G antenna system manufacturers in the search for low-priced system core, another consideration direction that may reduce the cost of modules. In this article, we will introduce the planning considerations of 4G antenna, the relevant main parameters, the types of 4G antenna and the use considerations on the product.
