Methods of constructing antenna arrays having a narrow beam width while providing a low level of side lobes are analyzed in the article. The patterns and the geometric dimensions of the antenna arrays based on patch antennas as radiating elements are presented. The method of constructing narrow beam antenna arrays, which solves the problem of too little spacing between elements, is described in the...
The effect of the thermodynamic strain-deformed states of a cavity antenna on its pattern and antenna matching with a feeder are investigated. The low single-mode cylindrical resonator with the aperture in the form of partially transparent flat surface is excited through coupling holes by the second resonator placed inside the first one. It is supposed that the wall with the radiating holes is heated...
