A printed circuit board comprises a substrate, a conductive layer, an antenna chip, a filter circuit and a wireless signal processing module. The substrate is made of an insulation material and the upper surface of the substrate comprises a first region and a second region; the second region is covered with the conductive layer; the antenna chip is arranged in the first region and used for sending and receiving wireless signals; the filter circuit is arranged on the second region, connected with the antenna chip through a connecting wire and used for filtering the wireless signals received by the antenna chip; the wireless signal processing module is arranged in the second region, used for processing the wireless signals and achieving the wireless communication function, and connected with the filter circuit through a connecting wire. The invention further provides an electronic device. The printed circuit board and the electronic device are simple in structure, cost is saved, and the influences of electromagnetic radiation on the signals received by an antenna module are reduced.
Description
technical field [0001] The present invention relates to a printed circuit board (PCB), in particular to a printed circuit board and an electronic device with the printed circuit board. Background technique [0002] With the development of wireless communication technology, more and more consumer electronic products have wireless communication functions such as Bluetooth, WiFi, and GPS, so that users can enjoy rich network resources. In the prior art, an independent antenna module and an independent wireless network signal processing module are generally set up, and then the two independent modules are connected through a coaxial wire. Therefore, it is necessary to install the antenna module and the same Axis wires are positioned and lined. Like this, not only reduced production efficiency, and increased the cost of product. In addition, since the coaxial wire has a certain length, the electromagnetic radiation intensity is increased to a certain extent. Contents of the i...
