FIELD: radio engineering. SUBSTANCE: device has odd number of emitters which are spaced by equal-size gaps, central emitter, which is designed as square, which side equals to half of wavelength. Middle emitters are designed as rectangles, which sides equal to half of wavelength and wavelength respectively. Other emitters are designed as square, which side equals to wavelength. Central emitter is excited in its angle, middle emitters are excited in middle of wave side edge by exciting elements, which are joined by power supply wiring, which is designed as cross-like connection of microstrip lines. EFFECT: equal conditions for reception of linear-polarized signal with arbitrary vector direction belonging to range of 0-90, in transmission mode they have slope of 45, shape of beam pattern is needle-like or funnel-like. |
