An electromagnetic band gap (EBG) metamaterial construction is presented. A construction of a multipath mitigating ground plane, based on the EBG metamaterial is described. A method of the ground plane application and installation, which provides the multipath mitigating without spoiling antenna element phase center stability, is suggested and explained. A designed construction of GNSS antenna module, which contains the multipath mitigating ground plane, made from the presented EBG metamaterial and installed in the described way is shown and parameters of the antenna module are provided.
Аннотация. В статье предложены оригинальные методы конструирования навигационных антенных модулей для аппаратуры глобальной навигационной спутниковой системы (ГНСС). Используется бескорпусная технология производства антенных моду-лей с применением метаматериалов в антенном элементе, улучшающих его характеристики, специальный EBG-метаматериал и метод его установки в геодезическом антенном модуле для снижения эффекта многолучевости, совместное применение бескорпусного антенного модуля с навигационным приемником. Рассматриваемые в статье подходы к проектированию на-вигационных модулей приводят к минимизации габаритных размеров, снижению стоимости производства, технологичности изделий, улучшению технических и эксплуатационных характеристик. 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.
