Abstract. Problems of modeling and design of an important
element of integrated microwave optics – matrix radiator are considered. An
array of E – plane planar horns excited by double-sided slot waveguides and
array H – plane horns excited by microstrip lines are investigated. Arrays are
analyzed in frames of models of different level: physical optics method,
solution of boundary problem in approximation of two – dimensional waveguide
model, solution of three – dimensional boundary problem with help of a system
of electromagnetic modeling FEKO. Arrays of finite length are considered.
Patterns of horn radiation in waves of planar waveguides are studied. Effects
caused by array finite length and horn length are investigated. Tolerance of a
model based on the physical optics method is analyzed.
Keywords: integral microwave optics, planar mirror,
planar lens, planar horn, array of planar horns.
