A new approach to integrated horn antenna

As millimetre-wave systems are becoming increasingly important in many scientific and military applications, there is an increasing demand of various antennas for communications, radar or sensoring system. This is particular true for the research on short-range application such as local multipoint distribution system (LMDS), commercial airplane landing system used in low-visibility weather, automobile cruise control system and so on. Some recently developed integrated horn antennas showed attractive features in [1][2] for application mentioned above, nevertheless they are too expensive for widespread application.
