ABSTRACT:
A monopole antenna adapted for efficiently radiating energy over an enhanced range of frequencies. The antenna includes a vertically inclined wire approaching one-quarter wavelength of said range of frequencies and a number of small-sized inductors installed along the length of said wire. The inductors are spaced apart so as to have negligible mutual coupling and are sized sufficiently small so that they do not have individual resonances over the range of frequencies for which the antenna is operational. The inductors provide a distributed reactance which allows the antenna to operate with greater efficiency over a broader range of frequencies.
