Abstract :
The radiation from a metamaterial spiral (MTSP) is investigated. The MTSP radiates a left-handed circularly polarized (CP) wave, a right-handed CP wave, and a linearly polarized (LP) wave. Effects of antenna size on the antenna characteristics, including the radiation pattern, axial ratio, polarization, and gain, are discussed.
