Research on Multi-Beam Focusing Antenna for Passive Millimeter Wave Imaging System
The application of millimeter-wave imaging technology in the security surveillance fields has currently become one of the most popular research directions. In the millimeter- wave imaging system, focusing antennas with large aperture and small focal diameter ratio are preferred to improve the spatial resolution. This paper has investigated the design of two types of multi-beam focusing antennas including a lens antenna with a focal diameter ratio of1.25 and an Ellipsoid reflector antenna with focal diameter ratio of 0.88. Simulations and experiment results have showed the change of the focal spot on the antenna axis and target plane each when the antenna feed is located at the focal point and offset-focusing. A millimeter-wave imaging system has been constructed and verified by the experiment.
