Abstract

This paper presents Japan’s enterprising project to develop the active phased array antenna (APAA) for practical applications. The objectives are to realize the cost reduction, small volume and light weight of APAAs at K-band frequency. The key technologies for those purposes are partial drive of an array, Monolithic Microwave Integrated Circuits (MMIC), a phase shifter with Radio Frequency-Micro Electro Mechanical System (RF-MEMS) switch and relevant control circuits, and system integration of all devices. The structure
and the research and development (R&D) schedule of the project are explained. The results of R&D activities so far are also described.
