Abstract :
The circularly polarized radiation characteristics of a bowtie-shaped grid array antenna (BTS-GAA) are investigated in order to broaden the area of application. It is found that a circularly polarized beam is obtained by appropriately choosing the amplitudes and phases of the feeding voltages. It is also found that the BTS-GAA acts as an antenna of dual circular polarization.
