Abstract
This paper presents a wideband circularly polarized planar antenna element for both K and Ka bands. The proposed solution is composed by several thin layers of dielectric substrate that allocate two circular stacked patches, a crossed-slot and two fork-shaped feedings. This antenna element is a good candidate for developing high-gain antenna array for the next generation of multimedia services in Ka band.
