Abstract

PURPOSE:To enable the tracking, by coinciding the beam direction of the com1unication antenna in the frequency band used both for the communication and tracking with the antenna base direction, increasing the gain used for the communication, and using the beam of TEM, TE2 1 mode synthesizing mode.
