Presents frequency dependencies of surface impedance near an array of rectangular waveguides when incident to flat electromagnetic wave, computed on a PC are shown. When placing radiant strips over an optimized waveguide array, contact ratio in frequency up to 2 and more …
In the article [1] two requirements for radiant strips (RS) of a wideband wide-angle antenna array (AA) are formulated: they must have small electric sizes and be located in a plane, wave impedance Z of which satisfies the condition , where W=120π — wave impedance of the free space, in the entire working area.

In the article Green's tensor function has been used as a basis to get the expression for the radiation pattern of a rectangular waveguide radiator array located on an infinite perfectly conducting wedge. The obtained expression has been analyze, which has made it possible to calculate the integral in a complex plane with the help of the saddle-point method.
