Investigation of Some Electrically Small Coincal Log-Spiral Antennas

reportActive / Technical Report | Accession Number: AD0736500 | Open PDF

Abstract:

The report is concerned with an evaluation and an experimental study of the radiation patterns, power gain, and voltage standing wave ratio of balanced and unbalanced spiral antennas when operated at wave-lengths much longer than would be considered normal for this size structure. The unbalanced antenna which was studied was a bifilar logarithmic spiral constructed on a dielectric cone with an inner metal core to house electronic equipment. At the base, one arm is bonded to the core.
