Abstract :
Summary form only given. A circular polarization Yagi-Uda antenna has been designed which is an extension of a tripole antenna. Several parasitic tripoles of unequal lengths are added in front of an active tripole or a large ground plane. Attention is focused on an antenna with a wire reflector. An integro-differential equation has been developed for the analysis of the circular polarization Yagi-Uda antenna array. Compared with an isolated tripole antenna, the present antenna exhibits a higher directivity.<>
