1、What is RF?
  Radio Frequency (RF) is the abbreviation of Radio Frequency, which indicates that the electromagnetic frequency that can be radiated into space, the frequency range from 300kHz to 300GHz. RF is radio frequency current, RF for short, it is a high-frequency AC change in electromagnetic waves for short. The alternating current that changes less than 1000 times per second is called low frequency current, and the one that changes more than 10000 times is called high frequency current, and RF is such a high frequency current. RF (300K-300G) is the higher frequency band of high frequency (greater than 10K), and microwave band (300M-300G) is also the higher frequency band of RF. In electronics theory, current flows through a conductor, a magnetic field is formed around the conductor; alternating current passes through the conductor, an alternating electromagnetic field is formed around the conductor, called electromagnetic waves. When the electromagnetic wave frequency is lower than 100kHz, the electromagnetic wave will be absorbed by the ground and cannot form effective transmission, but when the electromagnetic wave frequency is higher than 100kHz, the electromagnetic wave can propagate in the air and be reflected by the ionosphere at the outer edge of the atmosphere, forming a long-distance transmission capability. We call high-frequency electromagnetic waves with long-distance transmission capability radio frequency. RF technology is widely used in the field of wireless communication, and the cable TV system is using RF transmission method.

2、What is the working principle of RF antenna and antenna? ：
A, the principle of antenna
1.1 Definition of antenna:
Can effectively radiate electromagnetic waves to a specific direction in space or can effectively receive electromagnetic waves from a specific direction in space device.
1.2 The function of the antenna:
Ø Energy conversion - guided wave and free space wave conversion.
Ø directional radiation (reception) - with a certain direction.
1.3 Antenna radiation principle

二, the principle of radio frequency
2.1 The most basic RFID system consists of three parts:
2.2. Tag (Tag, that is, RF card): by the coupling components and chip composition, the tag contains a built-in antenna for communication with the RF antenna between;;
2.3. reader: read (in the read-write card can also write) tag information equipment;
2.4. antenna: in the tag and reader between the transmission of radio frequency signal. Some systems also through the reader's RS232 or RS485 interface and external computer (the main system of the upper computer) to connect to exchange data.

3、What is the RF connection cable (RF jumper)? ：
RF connection line (RF jumper) RF cable assembly by the RF coaxial connector and flexible cable or semi-rigid, semi-flexible cable combination made, widely used in microwave equipment and digital communication equipment. In the RFID system, also need a large number of RF cable assembly (such as the connection between the reader and the antenna). Cable assembly for the cabinet and the module between, RF cable assembly by the RF coaxial connector and flexible cable or semi-rigid, semi-flexible cable combination made, widely used in microwave equipment and digital cabinet and cabinet between, between the antenna and the feeder cable and the connection between the feeder cable and the cabinet. There are many types and varieties of cable assemblies, and users can choose the standard cable length, but also can propose special requirements of the specification length
