Abstract

A spiral slot antenna consisting of a single arm is etched into the upper plate of a triplate transmission line. Power on a feed strip line located between the upper and lower plates of the triplate is electromagnetically coupled to the spiral slot. The configuration of the spiral slot is optimised for radiation of a circularly polarised wave. An array antenna consisting of spiral slots, to which a pair-element technique is applied, shows wideband characteristics for the return loss and axial ratio.
