Abstract:
1. A compact dual-channel antenna operating at least in two frequency bands, a high-frequency band [F sup1 , F sup2 ] and a low-frequency band [F inf1 , F inf2 ], comprising: a coaxial cable connected to a reference ground plane (M) comprising a core and a braid, the coaxial cable is wound around a magnetic element to form a winding, a first antenna element designed to operate in the high-frequency band [F a counter-skirt with a length substantially equal to L an assembly including the second antenna element and the counter-skirt, having a length L said first antenna element being fed via the outside of the braid of said coaxial cable, at a tapping point, P, and a first wideband matching cell and a second wideband matching cell, wherein signals of the high-frequency band are transmitted via the braid of the coaxial cable forming a coil through the first wideband matching cell and the tapping point P, and wherein signals of the low-frequency band are fed via an inside of the coil through the core of the coaxial cable through the second wideband matching cell.
