Basic Antenna Parameters Theory. The Antenna from the transmission line as a 2-terminal circuit element having an impedance Z with a resistive component called the Radiation resistance Rr, while from space, the antenna is characterized by its radiation pattern or pattern involving field quantities. The Radiation resistance Rr is not associated with any resistance in the antenna proper but is a resistance coupled from the antenna and its environment to the antenna terminals.
