Abstract:

Semitransparent screens for cut-off of the field in the non-working angular area of the antenna (the shadow domain) have been considered. The screens could be called parallel to the main lobe direction. It has been shown that it is the distance from the source to the screen and the radius of the screen that defines the achievable cutoff in flat and concave cases correspondingly. For relatively large screen sizes in the approximation of geometric optics (GO), an analytical procedure for synthesis of the screen impedance has been formulated, which provides a purely real impedance. Beyond the limits of applicability of the GO approach, the numerical procedure to synthesize realizable complex impedance has been developed. Estimates for cut-off for wide angle and narrow beam antenna cases have been shown. The prototype of a compact antenna system has been developed.
