Sergey N. Boyko has been working in the patent research and patent licensing since 2004.
Since 1991 had been taking part in science-research work in the area of navigation, in particular antenna and feeder devices, laboratory centers for measuring antennas and antenna arrays, patent research in principally new UHF subjects.
 At the present time manages the science-manufacturing complex, which works at antenna module and small size antenna elements, based on metamaterials, researching and production for applications in navigation apparatus GLONASS.
During the work makes a personal contribution to the protection of the results of the intellectual work and technologies on priority directions of development of space systems and complexes of new generation.
He is the author of 24 science works (articles and reports) and 13 inventions, in particular used in the space technique.

Report Annotation. Constructive and technological methods of miniaturization of active antenna modules (AAM) of global navigation satellite system (GNSS) consumer’s equipment (CE) are suggested. AAM contains a microstrip antenna (MSA), low noise amplifier (LNA) and (totally) a navigation receiver chipset.
 Taking as an example several samples, serially manufactured in “ISDE” Co. Ltd., an innovative constructing-technological method of low-size antenna module realization, which idea is in integrating of all three AAM components, mentioned above, in composition of a union construction element, realized in a form of a ceramic or ceramo-compose case, is demonstrated. In this case all UHF components are placed inside a shielded space, isolated from the external EM fields influence. In case of installing a receiver chipset in the AAM case, a digital signal is formed on the output, which allows solving some problems of electromagnetic compatibility. Advantages of this decision, which are module size optimization and its exploitation characteristics improvement, are demonstrated.
 On some samples advantages of using metamaterial in construction of AAM, especially geodesic, are demonstrated. In geodesic AAM because of found metamaterial topology and special construction of metamaterial shield not only the reflected signal receiving was significantly (up to -40 dB) decreased, but the same time the antenna element radiation pattern wide form was preserved. That means that it was a success to separate the task of forming the geodesic AAM antenna radiation pattern in the top hemisphere and the task of reflected signals suppression in bottom hemisphere.
