Cellular /WiFi multi-band embedded flexible PCB antenna
It is equivalent to pulling out the antenna line on the PCB board and using other external metals to do the antenna. It is usually used in medium and low end mobile phones with complex frequency band and smart hardware products.
Advantages: suitable for almost all small electronic products, can do more than ten frequency band of complex antennas, good performance, low cost.

There is also the need for electronic products, including mobile phones, air conditioners, and electric fans that we use in daily life, which are used in small toys that children use to play. The widespread use of patch capacitors also leads to shortages in the market. price.
Based on the above analysis, in 2018, the SMD capacitor will continue to rise in price, and the specific rise to the current Xiaobian still does not know.

Disadvantages: need to be debugged separately for each product.
SMD capacitors have been out of stock until the second half of 2017, especially the shortage of individual models is particularly serious, mainly 0603 0805 series, 104,105,475,225,106,476 a few capacitance is particularly out of stock. The shortage of the SMD capacitor market caused its price to rise again. Of course, the current situation that caused these problems is also due to the fact that the cost of labor is getting higher and higher, and the high cost of machinery and equipment has evolved into the shortage of goods and the price increase of market models.
PCB antenna is widely used in Bluetooth module, WiFi module, ZigBee module and other single-band module circuit boards.
Advantages: the cost is very low, a debugging without debugging again.
Disadvantages: suitable for single band, such as Bluetooth, WiFi. Different batches of PCB antenna performance will have certain deviation.
