Dependence of the lateral and cross-polarized radiation reflector antennas on their size and focal length
Pattern in all planes of observation in the front half, gain, efficiency antenna area, the width of the main lobe, the levels of lateral and cross-polarized radiation axially symmetric parabolic antennas are designed by method of currents the physical theory of diffraction. The is given in the form of the approximate mathematical model within the aperture theory. Shading focal unit in the algorithm and computer programs recorded. It is shown that the system is a reflector + irradiator can be optimized for maximum gain when a predetermined maximum level sidelobes. influence of the size of a parabolic (in the calculation of the diameter varied from 10 to 100 wavelengths) and its focal length (focal length to the diameter of the was varied from 0.5 to 3.0) studied in detail. It is shown that in the case of antennas optimized maximum level and cross-polarized radiation is weakly dependent on the diameter of the and decreases with increasing depth of the reflector.
