WebThe effective electrical length of an antenna can be changed without changing its physical length by adding reactance, (inductance or capacitance) in series with the antenna. This is called lumped-impedance matching or loading. For example, consider a monopole antenna and a monopole antenna with a top hat of the same physical length. WebSo there is no phase difference in voltage and current. With an inductive or capacitive load, there is a phase shift.
