近年来，由于世界上通信系统的快速发展，预计微波频率将变得越来越紧。为了解决这一问题，日本总务省（MIC）正在积极利用被称为“高微波”的6 GHz ~ 30 GHz频段。主要应用被认为是移动应用、卫星通信和无线局域网。有源相控阵天线（APAA）具有先进波束控制的敏捷性，是该系统的关键技术之一。相控阵天线（PAA）在雷达中得到了广泛的应用。另一方面，由于相控阵天线在辐射波束控制方面的灵活性，在通信领域进行了很多尝试，但大多数都没有投入实际应用。
Recently, microwave frequencies have been forecasted to become tighter due to the rapid growth of communication systems in the world. In order to solve this situation, the frequency band from 6 GHz to 30 GHz which is called high microwave band is promoted for positive utilization by the Ministry of Internal Affairs and Communications (MIC) in Japan. Main applications are assumed to be mobile applications, satellite communications and wireless LAN. One of the promising key technologies for those systems is active phased array antennas (APAA) which have the agility of advanced beam control. Phased array antennas (PAA) have been vigorously utilized in radars. On the other hand, there were many attempts to use phased array antennas in communications due to the agility in radiation beam control, but most of them were not put into practical uses.
