Notes on the Design of Flat Screens for UHF Directive Antennas
Abstract
An investigation has been made to determine the effects of screen size, element spacing from the screen, and type of screening upon the amounts of back radiation and pattern distortion in the case of an antenna array consisting of parallel elements equally spaced from a flat reflecting surface. Measurements were taken using a half wave dipole and a flat reflecting screen and the results permitted the determination of the optimum screen size and type of screening for the case of an array with a flat screen. Measurements were made at 400 Mc and conclusions reached would not necessarily be applicable for frequencies widely differing from this.
