The features of radiation pattern characteristics of microwave planar slot antennas with linearly increasing aperture

Radiation patterns of planar symmetric slot antennas of microwave range (the central frequency f0 = 10 GHz) with linearly increasing aperture of constant length (5λ0 = 150 mm) were get by means of theory and experiment in E and H planes for fixed values 10˚, 22˚, 30˚, 34˚ and 60˚ of aperture angles. The limits of applicability of model concepts of investigated antennas were established on the base of experiment data. They were almost invariable at the boundaries of range 6-12 GHz.
