Abstract :
A monofilar rectangular metamaterial spiral (MTM SPA) is composed of a ground plane, a dielectric substrate, a conducting spiral arm with capacitors and inductors. The height of the spiral arm above the ground plane is extremely small: approximately 0.01 wavelength. The MTM SPA acts as a counter circularly-polarized radiation element (anti-CP radiation element). This paper discusses the effects of the pitch and the ground plane size on the antenna characteristics. The squint of the radiation is also discussed.
