Navigational Antenna Modules of the GNSS Equipment

Abstract

The article describes original design methods of navigational antenna modules for the global navigation satellite system (GNSS) equipment. The uncased technology for antenna modules production using metamaterials in the antenna element improving its characteristics, special EBG-metamaterial and a method for its installation into the geodesic antenna module to reduce the multibeam effect, common application of an uncased antenna module with a navigational receiver are used. The approaches to the design of navigational modules result in overall dimensions minimization, production cost decrease, items manufacturability, and improved technical and operational characteristics.
