An antenna lead-in is the transmission line (or feed line) which connects the antenna to a transmitter or receiver. The <answer>antenna feed</answer> may refer to all components connecting the antenna to the transmitter or receiver, such as an impedance matching network in addition to the transmission line. In a so-called aperture antenna, such as a horn or parabolic dish, the "feed" may also refer to a basic antenna inside the entire system (normally at the focus of the parabolic dish or at the throat of a horn) which could be considered the one active element in that antenna system. A microwave antenna may also be fed directly from a waveguide in place of a (conductive) transmission line.
What is the group of elements used to join the elements of an antenna?
