Design of a Continuous Resistively Loaded Monopole Antenna

Authors: Darwish A. Mohamed; Ramakrishna Janaswamy; NAVAL POSTGRADUATE SCHOOL MONTEREY CA DEPT OF ELECTRICAL AND COMPUTER ENGINEE RING
Abstract:
Hallen's integral equation with continuous resistive loading is used to design a broadband monopole antenna. The resistive profile is different from that of the well known Wu-King profile and results in a higher efficiency compared to the latter. An optimization function for determining the optimal continuous resistive load of the monopole antenna in order to satisfy the broadband property is constructed. Simplex method is used to perform the optimization. The integral equation is solved by the moment method to determine the current distribution, the efficiency, and the radiation pattern of the monopole
