For example, an antenna could be designed to sit on top of a metal surface (or an impedance matching network), our antenna will not work properly.īefore we begin, I'd like to point out that objects placed around the antenna can alter its radiation Will be received by the antenna (if used in the receive mode). Will be transmitted by the antenna (if the antenna is used in the transmit mode), or very little power If the impedance of an antenna is not 'close' to that of the transmission line (most often 50 Ohms), then very little power In this section, we'll be concerned with measuring theĪs stated previously, the impedance is a fundamental parameter for antennas.
