Abstract
A loading technique that combines both resistive and inductive tapered loadings to improve the efficiency of the monopole and yet maintain uniform nonresonant impedance characteristics which makes a good impedance match possible, is introduced. In order to increase the radiating power and thus the efficiency of the resistively tapered monopole, tapered inductive loading is employed primarily to counteract the high capacitive reactance at the lower end of the frequency band and thus increase the radiating power of the antenna. Several profiles for the inductive loading were tested and were found to give, depending on the load, an improvement in the radiation power of the antenna. However, only one among the different loading profiles used was able to increase the efficiency and yet maintain very favorable broadband matching characteristics.<>
