Abstract :
An approximate expression is derived for the phase velocity of wave propagation along an infinite Yagi structure with its conventional constituent dipoles replaced by short helices operating in their normal mode. It is theoretically predicted that the proposed infinite Yagi structure acts as a slow wave structure.
