Abstract

PURPOSE:To realize the antenna of light weight by a simple feeding system through the use of less number of elements, by performing beam polarization with broader angle to one direction and by polarization by about beam width to orthogonal direction. CONSTITUTION:The reflection mirror 11 constitutes parabola shape and the feeding arrays 12a, 12b are placed at the location near the focus of the reflection mirror 11. Further, the flat type electromagnetic wave lenses 13a, 13b are provided corresponding to the arrays 12a and 12b, and the power distributor 14 is inserted between the feeding terminals 15a, 15b of the same azimuth of the lenses 13a and 13b so that the power ratio between terminals can be changed. Thus, the beam polarization is made in broader angle to one direction and the polarization by about beam width is made to the direction orthogonal to it, to realize the antenna of light weight with a simple feeding system by using less number of elements.
