Blinova N. Electromagnetic waves scattering on slot systems in waveguides with arbitrary loads

Object of research: scattering and radiation of electromagnetic waves in rectangular waveguides with slot radiators. The purpose of research: the revealing and mathematical simulation of physical regularities of radiation and scattersng of electromagnetic waves by systems of waveguide- slotted radiators consisting of single, X-type and coupled slots in waveguides with arbitrary loading. Methods of research: the theoretical results were obtained using specially modified method of successive approximations. Theoretical and practical new results: The choosing of reflecting coeficient from a load can improve antenna matching with feeder, reduce side lobe level, increase axis ratio of circularly polarized field. The doubled slot situated near waveguide wide wall axis is a narrow-band high- effective radiator. The result s of the work can be used for creation of waveguide- slotted antenna arrays. It is proposed the simple method of tuning waveguide- slotted antenna for circular polarized field radiation by regulation of end load. The field of application: the technique of the centimetere and millimetre ranges of wave band.
