STUDY AND INVESTIGATION OF A UHF-VHF ANTENNA
Abstract
The theoretical study of plane-wave diffraction by a ferrite sphere has been extended to (1) evaluate the effect of higher modes, (2) map the lines of power flow, and (3) treat the case of an enclosed, perfectly conducting sphere. The theoretical study of plane-wave diffraction byA FERRITE CYLINDER HAS BEEN EXTENDED TO TREAT THE LONGITUDINALLY MAGNETIZED CASE. An analysis of the resonance condition for the shielded, balanced-loop antenna immersed in a ferrite medium has been made. Conditions for maintenance of resonance over a broad frequency range have been obtained and found to be fairly consistent with the published properties of known ferrite materials. The analysis suggests the possibility of tailoring ferrite properties for broadband use in microwave components and antennas. Experimental results of the measurement of ferrite materials are given.
