WIFI probe overview When one device sends information to another device through wireless transmission technology, other similar devices around it can receive wireless information. The WiFi probe technology is based on this principle. Specifically, when the WiFi device is within the listening range of the WiFi probe, when the WiFi device (whether a terminal, a router, or other WiFi device) transmits any frame, the probe can be intercepted regardless of the sender. And analyze some information of...
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 on-board type: integrated with PCB etching, limited performance, very low cost, applied to Bluetooth, WIFI module integration; (2) SMT mount type: the material is ceramic, metal sheet, PCB, and the performance cost is moderate, suitable for...

Car radio antennas are becoming a standard component in automotive design. Atmel's antenna amplifier chip specifically addresses this challenging small and micro antenna design trend while maintaining the reception of car radios. The development prospects of modern car antennas have raised some technical requirements and constraints that are more difficult to deal with. Among them, the most important and most challenging requirement is to reduce the size of the antenna; secondly, the length...
As an electromagnetic transducing element, the position of the antenna in the entire radio communication system is very important, and the quality directly affects the distance between the transceiving distance and the interlinking effect. It can be said that without the antenna there is no radio communication. As a classic directional antenna, Yagi antenna is widely used in HF, VHF and UHF bands. It is called "Yagi/Uda antenna". This article first introduced the principle of the Yagi...

Researchers at the University of Manchester have found a way to use graphene to print out antennas on clothes. This method is cheaper and more flexible than traditional methods of making antennas from metal, and the conductivity can be increased by nearly 50 times. Graphene is a single layer carbon atom material whose overall thickness is only one atom in diameter. Scientists proposed that the theoretical hypothesis of graphene has been around for decades, but it was not until 2003 that Andre...
