APPARATUS OF FIXING A MAIN-BEAM OF A BROADBAND SERIES-FED ARRAY ANTENNA

摘要

PURPOSE: A main beam fixing apparatus of a broadband serial antenna for compensating the phase variation of an electromagnetic wave are provided to improve the radiation efficiency of the antenna by using serial network in the antenna. CONSTITUTION: Unit cells of a series-feeding array antenna includes a transmission line(10), a radiation device(11), an amplification circuit(12) and a reverse wave circuit(13). The radiation element radiates a part of the wave. The amplifier circuit amplifies the intensity of the radiated wave. The returning wave circuit recompenses the phase change of the wave due to the radiation element and transmission line. The returning wave circuit outputs the compensated wave.
