Title (EN) MULTIPLE ANTENNA SYSTEM
(FR) SYSTÈME À PLUSIEURS ANTENNES
Abstract:
(EN) The present invention relates to an antenna system (100) including at least two antenna modules (110, 120) operable for transmitting and/or receiving radiation in certain common frequency band. The at least two antenna modules (110, 120) are collinearly arranged along a common axis so as to provide low gain along the axis, and are spaced apart from one another along this axis by a distance of at least a few nominal wavelengths of the common frequency band. Each two locally adjacent antenna modules of the at least two antenna modules (110, 120) operate with substantially mutually orthogonal polarizations of radiation, thereby suppressing electromagnetic coupling between the antenna modules in the common frequency band.
(FR) La présente invention se rapporte à un système d'antennes qui comprend au moins deux modules antennes servant à émettre et/ou à recevoir un rayonnement dans une certaine bande de fréquences commune. Lesdits modules antennes sont alignés le long d'un axe commun afin de générer un faible gain le long de cet axe, et ils sont espacés sur cet axe en respectant une distance au moins égale à quelques longueurs d'onde nominales de la bande de fréquences commune. Chaque paire de modules antennes localement adjacents parmi lesdits modules antennes fonctionne avec des polarisations de rayonnement qui sont presque mutuellement orthogonales, ce qui évite le couplage électromagnétique des modules antennes dans la bande de fréquences commune.
