Antenna design WIFI detailed tutorial

As market competition intensifies, hardware devices are developing in an integrated direction. Antennas have also evolved from external evolution to embedded, and we will first introduce the types of antennas for this type of application:

(1) On Board onboard: integrated with PCB etching, limited performance, very low cost, used in Bluetooth, WIFI module integration;

(2) SMT mount type: the material is ceramic, metal sheet, PCB, and the performance cost is moderate, suitable for high-volume embedded RF modules;

(3) IPX external connection: use PCB or FPC + Cable combination, excellent performance, moderate cost, widely used in OTT, terminal equipment;

(4) External external category: plastic rod antenna, high performance, independence, high cost, applied to terminal equipment, no need to consider EMC and other issues;

External antennas are well known, so let's take a look at the space required for the three types of built-in antennas:

Let's summarize the space requirements and performance indicators:
