About the features of radiation pattern of the symmetric slot antennas in microwave range

Features of radiation patterns of antennas on the basis of planar symmetric slot lines of constant width at a frequency of 10 GHz, in the E and H planes in case of change of their length and width were studied. The comparative analysis of mathematical modeling results and results of an experiment has shown that at increase of a regular slot width within 0,5 to 1,5 or 1,5 sm to 4,5 sm, the level of half power beam width of the main lobe in the E plane was narrowed, while it remained almost invariable in the H plane.
