Sažetak

The cross antenna is a printed structure of average profile and circular polarization, which consists of a conductor or tape on a ground plane that follows the contour of a cross with four or more arms and a diameter of about 1.5 wavelengths developed by Antoine Roederer. The antenna is feeded by means of a coaxial line and is finished in an impedance of load, for what it is represented by a behavior of travelling wave. Though in principle the antenna was designed for applications in mobile communications in Band L (1500 MHhz), we present in this work the experimental characterization of an antenna of cross of eight arms that is employed at 10 GHz, with the principal intention of serving as feeder of a parabolic reflector for satellite communications.
