{{main|Helical resonator}}
A helical resonator is a [[helix]] of wire in a cavity; one end is unconnected, and the other is bonded to the cavity wall. Although they are superficially similar to lumped inductors, helical resonators are distributed element components and are used in the [[VHF]] and lower [[UHF]] bands.<ref>{{multiref|Whitaker, p. 227|Doumanis ''et al.'', pp. 12–14}}</ref>
=== Taper ===
A taper is a transmission line with a gradual change in cross-section. They are a simple way of joining two transmission lines of different characteristic impedances. Using tapers greatly reduces the mismatch effects that a direct join would cause.<ref>Garg ''et al.'', pp. 180–181</ref>
