Introduction of Antenna
The antenna is a device that transmits radio frequency
signals from the coaxial cable radiation source to the air or from the air to
the coaxial cable. waves. If you choose the wrong one, you will not get the
proper function, and maybe burn the module seriously.
For the design of a wireless network receiving and
transmitting device used in the radio system, the design and selection of the
antenna is very important. A good antenna system can make the communication reach
the best state. The antenna is positively related to the optical wavelength of
the radio frequency signal, the lower the frequency of the data signal, the
larger the antenna required.
l Classification
of Antennas
Antennas can be divided into external antennas and
internal antennas according to the installation position. The antennas
installed inside the equipment are called internal antennas, and the antennas
installed outside the equipment are called external antennas.
l Internal antenna
For small-scale products such as handheld devices,
wearable devices, and smart home systems, built-in antennas are widely used,
which have high processing speed and beautiful appearance. The Lora and smart
products must be connected to the network to transmit data, so antennas must be
used.
l External Antenna
External antennas are generally standard materials. You
can use the antenna with the required frequency band without adjustment.
For example, forwarder boxes and vending machines,
external antennas with magnetic are widely used, which can be absorbed on the outer
case of machine. This kind of antenna cannot be placed inside the machine,
because the metal material will shield the antenna signal, so it can only be
placed outside.
