Abstract :
This paper presents the design and measured performance of a new circular-polarized array antenna. The antenna maintains an excellent radiation pattern with axial ratio less than 1 dB across a bandwidth greater than 7 percent in the Ka-band. The design should be especially useful for millimeter-wave communications applications.
