The real part of the impedance of this antenna is about 15-25W, depending on geometry and proximity to the
ground plane. The impedance matching is done by adjusting the length of the antenna until the input impedance
is at the unity conductance circle (when normalised to 50W), in the top half of the Smith chart (Point A). A shunt
capacitor is then connected between the antenna input and ground to match to 50W (Point B). Experimental
measurement is used to determine the correct design.
