Does An Antenna Need Power at Phillip Early blog

Does An Antenna Need Power. An antenna needs power to radiate and a proper length to excite at given frequency. An antenna’s input impedance refers to the amount of opposition mounted against the flow of current through its conductive. Now for am, the wavelengths are about 100 times greater, so how come you don't need an antenna that's 300m (0.2 miles) long to. An infinitely thin (very, very thin wires) dipole antenna (with apparently no physical area to catch radiated power coming its way). In transmission, the radio transmitter provides electrical current to the terminals of the antenna and the antenna emits energy from the current as electromagnetic waves (radio. In summary, an active antenna does indeed need power to operate effectively. Power gain refers to the power radiated in a particular direction when compared to the total power input. The length of antenna depends on frequency. The radiation efficiency of an antenna is the ratio of radiated power to input power.
