Comparison of advantages and disadvantages of PCB antenna, FPC antenna and LDS antenna
Compared with the external antenna, PCB antenna, FPC antenna, LDS antenna and other internal antennas have their own unique product form. These three can not be regarded as differences, each has its own advantages and applications.
一，PCB Antenna
Cellular /WiFi multi-band embedded flexible PCB antenna
PCB antenna is widely used in Bluetooth module, WIFI module, ZIGBEE module and other single frequency module circuit board.
Advantages: Low cost, no need to debug once.
Cons: Suitable for single band, such as Bluetooth, WiFi. Different batches of PCB antenna performance will have a certain deviation.
二.FPC Antenna
It is equivalent to pulling out the antenna line on the PCB board and using other external metal to make the antenna. It is usually used in mid – and low-end mobile phones and smart hardware products with complex frequency bands.
Advantages: Suitable for almost all small electronic products, can do more than ten frequency band complex antenna, good performance, low cost.
Disadvantages: Need to be adjusted separately for each product.
三， LDS Antenna
LDS antenna is the evolution of FPC antenna, space utilization is very high. FPC line is stamped out, must be flat, can not be stamped out of complex shapes. FPC antenna is a whole plane, although can bend, but also can not do too complicated. The LDS antenna uses lasers to carve out the pattern of the antenna, making it ideal for compact interior applications.
Advantages: Can make full use of all kinds of irregular surface in the three-dimensional space, reduce the volume of the antenna.
Disadvantages: The price is more expensive, an order of magnitude more expensive than FPC antenna, and there are many special requirements on the surface of the product process.
Therefore, the above three antenna characteristics are not absolutely good or bad, different customers, different product requirements of the antenna type is also different. Ultimately, you need to choose a suitable antenna. To meet the needs of the product, if you need antenna please choose us-MHZ.TD.
