Abstract :
In this paper we present a medium frequency (MF) band helical dipole antenna for borehole application. The proposed antenna is loaded with a ferrite-bundle and is optimized to achieve an ultra-compact size to fit within a volume of λ0/1337 × λ0/1337 × λ0/80 while maintaining a relatively high efficiency. To feed the antenna from the center using an external source, the effect of a metallic cylinder placed in the center is also examined.
