Ultra High Permittivity Dielectric Helical Resonators

This paper discusses the possibility of constructing a resonant element from ultra high permittivity dielectric material shaped into a helix. The modeling conducted shows that the mode associated with ceramic quarter wave resonators is present within a coiled dielectric helix providing the permittivity is very high. The properties of which are strongly dependent upon the thickness of the coils. Some of the helices studied in this paper are very compact and may possess moderate Q factors, due to the low filling factors.
