Electronic Scan at Millimetre Wave Frequencies (Electronische Bundelsturing Voor mm-Golf Radar)
Abstract
The possibilities of realizing phased array antennas in the mm-wave region is reviewed in a general way. The use of discrete components and 'bulk' material is discussed. The MMIC techniques for the realization of phased array components are excluded from this report. A survey is given of the different electronic scan possibilities. PIN diode phase shifters and different types of ferrite phase shifters are discussed, including the principle functioning of these components as well as the advantages and disadvantages. The availability of various ferrite materials for phase shifters is discussed. The requirements for phased array antennas and its phase shifters are given. This includes a discussion on array element spacing, side-lobe level and related power levels, effect of pulse repetition frequency and mutual coupling. An attempt is made to correlate all the available information at cm-wavelength (3-18 GHz) and to extrapolate it to mm-wavelength. All the detailed properties of the phase shifters are included. The experimental results of mm-wave phase shifters are given and compared the extrapolated results given. Netherlands.
