Abstract :
This paper presents a metaloop antenna, which radiates a dual-band counter circularly-polarized (CP) wave. The antenna characteristics, including the radiation pattern, gain, and VSWR, are discussed. The radiation efficiency is also discussed. It is found that the gain increases by 3.5 dB for the left-handed CP wave and 4.8 dB for the right-handed CP wave, when the antenna height is changed from 1.6 mm to 3.2 mm. The VSWR is small within the gain bandwidth, as desired.
