The broadband balun for an arc dipole is simplified as a 50-[ohm] lumped impedance since the input impedance (looking at point "A", see Figure 1) of the broadband balun was designed to be 50 Q.
Both define a lumped impedance, that in the case of an array of perfect conducting metallic disks, is capacitive.
It is assumed that antenna elements can be represented by lumped impedances, and Touchstone software is used to simulate and optimize the microstrip feed network under such conditions.
