Abstract :
A single feed dipole antenna to radiate a circularly polarized wave and to have a broad bandwidth has been introduced and its characteristics have been confirmed from both calculation and experiment. It is found that the axial ratio bandwidth (2/spl les/dB) of about 20% and the gain of 9 dB pre obtained.
