What Is an Antenna Coupler?
An antenna coupler is a device designed for impedance matching between an antenna and a radio transmitter or receiver.
This device optimizes the transfer of radio waves from the antenna to the radio system by utilizing electrical components like coils and capacitors. The goal is to improve reception sensitivity and transmission efficiency. Key components of an antenna coupler include tuning circuits, impedance conversion circuits, and matching networks, all working in tandem to synchronize the antenna’s impedance with that of the radio transmitter or receiver, thus enhancing radio wave transmission.
Antenna couplers are distinguished by their ability to boost transmission power, enhance reception sensitivity, and minimize the standing wave ratio (SWR). They are equipped with manual and automatic tuning adjustment capabilities, offering flexibility in optimizing communication signals.
