Abstract :
A curl antenna is designed using the metamaterial concept (left-handed property). The antenna radiates a circularly polarized (CP) wave, and has a small antenna height. When the antenna height is 1.6 mm= 0.016 wavelength at 3 GHz, the curl has an approximately 10% gain bandwidth. The rotational sense of the radiated CP wave below the balanced frequency is opposite to the arm winding direction.
