Driven and parasitic elements
From Wikipedia, the free encyclopedia
"Passive radiator" redirects here. For the speaker enclosure, see Passive radiator (speaker).
"Parasitic element" redirects here. For unwanted electrical circuit components, see parasitic impedance.
In an antenna array made of multiple conductive elements (typically metal rods), a driven element or active element (also called driven radiator or active radiator) is electrically connected to the receiver or transmitter while a parasitic element (or passive radiator) is not.
