Antennas(Mian Board is High Frequecny PCB / Radio Frequency PCB) for industrial wireless systems:
As one of the key components of industrial wireless system, antenna is a special equipment to convert the high frequency electromagnetic energy in the transmission line into the free electromagnetic wave in space or the free electromagnetic wave energy in space into the high frequency electromagnetic energy in the transmission line.So choosing a suitable antenna is very important for the performance of wireless network.
According to the direction of radiation, antenna can be divided into two categories: omni-directional antenna and directional antenna.
■ omni-directional antenna propagates in all directions.
■ directional antenna propagates highly in a very narrow "beam";More common are parabolic and yagi antennas.Each type has its own unique characteristics and applications
