Based on a recent remarkable development of digital beamforming (DBF) antenna technologies, we propose a new concept of kaleidoscopic antenna, we call it "software antenna," which is a more general one extending DBF schemes. The software antenna instantly reconfigures itself adapting its software and hardware to changes in the radio-environment. To realize the software antenna, the development of high-speed reconfigurable FPGAs is indispensable. As an intelligent antenna, we believe the software antenna could play a key role in the days of software radio having a function of mobile computing.
