Abstract :
A dual-band metahelical antenna that has a negative phase constant for the current on the helical arm is realized. A left-handed circularly polarized (CP) wave is obtained within a specific frequency band and a right-handed CP wave is obtained within a different frequency band. The antenna characteristics, including the radiation pattern, gain, and input performance (VSWR) are presented and discussed.
