Abstract

In this paper the development principles for calculation and construction of the antenna for «smooth» transmission and reception of multichannel ultra-wideband signals with a given spiral phase front applied in Radio-over-fiber system for the seamless data transmission are discussed. The detail description of the current state of research in this field is presented and deeply analyzed, so finally the new unique solutions are proposed and described in detail.Since the transceiver antenna has a significant effect on the signal shape working as a spatio-temporal filter, then the phase of the emitted wave (spin-orbital state) depends only on the antenna geometry. So the inverse problem of the antenna theory should be solved, when the antenna array configuration is synthesized on the basis of the given aperture.The antenna is considered as distributed in-space volume antenna arraybased on tripoles, providing the reception of a «tangled» signal with wave division and spin-orbital state multiplexing. The antenna is calculated using a mathematical and computer modelling and characterized with stable characteristics in the ultra-wide frequency band.
