Microwave-range broadband "Dark Eyes" antenna: detailed analysis and design

In this letter, we present a broadband antenna designed for microwave-range applications. The antenna is planar and the combination of its geometry with resistive loading results in its broadband behavior. For several values of surface resistive loading under investigation, we calculate the return loss, percentage distribution of the total incident energy and the radiated electric field fidelity. Finally, we discuss criteria for choosing the optimal surface resistivity and plot the corresponding radiation pattern.
