STUDY AND INVESTIGATION OF A UHF-VHF ANTENNA.
Abstract
During this report period, the most encouraging result was that found for the log conical antenna wherein the use of ferrite loading inhibited the biaxial mode operation of the antenna at the low frequency end. Because of this, it is possible to say that ferrite has truly extended the useful range of operation of this type of antenna utilizing the desired axial mode. Further encouraging results were witnessed with respect to the rectangular slot filled with ferrite and utilizing magnetic bias. Certainly all aspects of magnetic bias control have not been studied in detail as yet. However, the preliminary results show that it is possible to shift upward the center frequency of the operating band through the use of magnetic bias. The deterioration of efficiency is considered a tolerable one in view of the possibilities of operating over a wider frequency band. (Author)
