Gains of finite-size corner-reflector antennas

Equipment characteristics and their relation to system performance for tropospheric communication circuits

“…However, for the lower frequencies a standard horn is quite large and heavy, and the use of corner reflectors is recommended as described by Cottony and Wilson [ 1958] . Corner reflectors have the advantage that they are relatively light even at the lower frequencies, can be collapsed to lie flat, and can be so constructed that they can maintain their characteristics through many assemblies and disassemblies.…”

Impedance of a corner-reflector antenna as a function of the diameter and length of the driven element

“…On the basis of previously m easured gains [1]1 and radiation patterns [2] obtainable for cornel'-reflector antennas having various combinations of lengths and "W'idths, a Corncl' r efl ector havin g a length of refl ec ting planes, L j}.. = 1.0, wid th of r efl ecting planes, liVj}.. = 1.3, and an aper ture angle of 110° was selected . From fi gure 48 of reference [2] t he beamwidth can be seen to b e beLween 48° and 50° as r equired.…”

“…From fi gure 48 of reference [2] t he beamwidth can be seen to b e beLween 48° and 50° as r equired. The " first" dipole posiLion, distance from apex of com er reflector, for an aperture angle of 110° can be found in figure 3 of reference [1 ] to be in the range of 0.2}" to 0. 35}... Th e gain of a corncr-refleetor antenna wi th these parameters should b e approxim ately 12.2 db over an isotropic radiator.…”
