RECEIVE AND/OR TRANSMIT MICROWAVE PLANAR ARRAY ANTENNA AND USE OF SAID ANTENNA FOR RECEIVING GEOSTATIONARY SATELLITE TELEVISION SIGNALS

摘要

the antenna is a planar array antenna (1) of the type of pilemultiplaque and comprising a plurality of radiating elements to split (eri)arranged in the rows and columns of a matrix. the basic stackthe mass consists of three plates (12, 11, 10) with recesses (120) and twoplans (14, 13), (14), the excitation circuit (13) in order to be able totransmitting or receiving two beams inclined. according to the invention, include at leasttwo other areas of excitation circuit (17, 16), in such a way that eachin addition to the beam is polarized. the excitation circuit is formeda waveguide microstrip, coplanar lines dipoles, loops, orthe slit, or a combination of these. two consecutive lines are oriented to90 degrees.application in particular to the individual approval of two satellitegeo tv.
