Abstract :
This paper develops a directive circularly polarized wide band antenna. A distribution of parasitic dipoles is joined to a spiral antenna to enhance the forward circular radiation over a bandwidth more than 20%. The electromagnetic responses of the parasitic dipoles are optimized thanks to SMD inductors and capacitors welded onto the dipoles.
