Scientific problem. In antenna arrays with great number of emitters there is a problem of waveguide layout. There are several reasons for that: bounded space of antenna aperture and great number of waveguide elements to place in it; several types of waveguide transmission lines using in the antenna arrays. Nowadays existing computer-aided design systems doesn-t give an opportunity to solve the waveguide layout problem in corpore. Purpose of research. The main purpose of the research is to develop software module for waveguide layout. First of all it is necessary to define the criteria for the antenna arrays waveguide layout. Field of application. Automation of waveguide layout is actual especially for the ground-based large-sized antenna arrays. Some specifics of waveguide designing in a phased antenna arrays for the aeronautical communication. Geometrical, technological and radiotechnology boundary conditions review: 1) boundary conditions: antenna array aperture overall dimensions, metal constructions placement; 2) radiotechnology conditions: equality of the waveguide transmission lines geometrical length, minimum waveguide path length, minimum flange couplings and waveguide bends; 3) technological conditions: minimum waveguide length-s spectrum, waveguide transmission line symmetry; 4) stress-strain conditions: attachment points location, uniform of waveguides placement; 5) geometrical conditions: optimal number of waveguide transmission line-s plies, avoiding of objects crossing, rectangular waveguide section-s orientation. Summary. The waveguide layout conditions are considered. An algorithm for process automation should include: layout design of waveguide transmission line from a power divider to antenna emitters; waveguide transmission lines length optimization.
