<p>The system has two collinear dipoles (11, 12) operating in frequency bands (Fhinf, Fhsup and Fminf, Fmsup), respectively. The dipoles radiate when they are in their combined frequencies. The Fmsup frequency is higher or equal to Fhinf frequency. A monopole (13) operates in the band (Fbinf, Fbsup). A supply system has outputs (16-18) connected to dipoles (11, 12) and monopole (13) by transmission lines (21-23) respectively.</p> |
