Abstract
This communication reports the application of the Wheeler method for the measurement of the efficiency of differentially-driven microstrip antennas. The S-parameter method and the mixed-mode S-parameter method are both used to obtain the differential impedance with and without the cap. It is shown that although additional parasitic inductance and capacitance are introduced from the dual feeds, the parallel RLC model is the valid model to use for the measured probe-fed differentially-driven microstrip antennas.
