Technical Session I: Advanced Component Developments
Abstract
This paper is devoted to the new technologies of antenna system miniaturization and those technology implementation in space telecommunication and Earth remote sensing systems - for spacecraft, ground terminals and stations. Nowadays, an ability to transmit data bulks, generated by onboard equipment, becomes one of the essential performance of satellite system specifications. The conventional ways to solve the said problem result in increase of the weight and sizes of an antenna system, increase of the requirements to a power supply system, decrease of the width of antenna pattern, etc. The backlog in the technology of planar (flat) phased antenna arrays is a good basis for development of small-sized antenna systems. The authors managed to avoid a series of conventional disadvantages of the planar phased antenna arrays. The small-sized ferroelectric antennas technology is among advanced directions of antenna system development. The weight and sizes of ferroelectric antennas are smaller than those of the conventional ones in some an order of magnitude. This technology implementation in spaceborne planar phased antenna arrays would rise their efficiency. The possible applications of both planar and ferroelectric antennas in onboard and ground systems of space information transmitting/receiving have been considered.
