Abstract
An antenna adapted for satellite communication. A plurality of planer radiating elements are disposed under a ground conductor of a microstrip planar antenna, and the ground conductor is coupled with the respective radiating elements through electrically coupling means. Further, a plurality of linear radiating elements are coupled with the ground conductor and electrically connected to a sperrtopf applied to a coaxial line which acts as a feeder line. As an antenna used for satellite communication, it is possible to improve the gain at a low elevation angle in a wide angle circular polarization antenna.
