Horn aperture
WebAn aperture size of the double-ridged horn is less than a half of a wavelength. This special horn is applicable for active phased array antennas as an antenna element. WebAperture Fields The fields at the aperture of an E-plane horn will be assumed to be the same as those of the dominant TEIO mode of a rectangular waveguide whose dimensions are the same as those of the horn aperture.
