... GuidesArray Rectangular™ is created to facilitate managing directional diagram, increasing output, enhancing interference protection, and maximizing information extraction. It is known that thanks to the high transmission capacity and low–loss waveguide transmission line, phased array antennas provide excellent characteristics for centimeter wave band. To achieve maximum efficiency while using phased array antennas, a reliable computer–aided engineering system is required. To this effect,...

The thesis is devoted to designing broadband highly directional scanning antenna arrays based on waveguides with a complex (in general case, random) cross section working on a linear (vertical or horizontal) or double (orthogonal or circular) field polarizations in the monopulse mode. The aim of the thesis comes down to solving an important scientific ...

We present a method for matching waveguide radiators used in wide bandwidth phased antenna arrays with wide-scanning angle. In order to achieve matching, the following parameters are used: the geometrical parameters of waveguides, the dielectric parameters of materials inside the waveguides,...

It is presented the electrodynamics analysis of complex cross-section waveguide phased-array antennas with dual polarization. Energetic, polarization and frequency characteristics of cross-ridged circular and square waveguides as elements in phased-array antennas with dielectric covers and supports are studied. An analysis ...

Phased antenna arrays (PAA) of waveguides with complex cross sections are analyzed in this work. Particularly, the analysis focuses on linearly polarized waveguides with dielectric matching units (inserts, covers and waveguide transformers). The study of power and frequency characteristics ...

Equations for waveguide, impedance and lens antenna arrays are formulated taking into account excitation conditions and interconnection between radiators. The arrays can be located on flat or curved surfaces. Antenna arrays

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 sector of angles ±55° in main planes can be obtained. In ...
