Patent ID: 8922445

Claim:
A low-profile broadband multiple antenna comprising at least two dipoles (D k ), each dipole k designated D k consisting of a top antenna element D ks and a bottom antenna element D kb , said antenna being powered by a coaxial cable comprising a core and n sheaths arranged concentrically around the core, with k varying from 1 to n, comprising: a dipole D 1 (k=1) arranged in the top part of said antenna, said dipole D 1 comprising at least one first top antenna element D 1s connected to the core of said multi-axial cable comprising n sheaths and the bottom individual element D 1b of which is connected to the first sheath adjacent to the core, a connection device positioned between a top element D ks of a dipole D k (k>1) and the bottom element D kb of said dipole D k , the top element D ks is connected at a point to the sheath of index (k−1) of the multi-axial cable after the assembly comprising the core and the sheaths of index (1 to k−1) has been wound in Q turns around a magnetic core and the bottom element D kb of the dipole D k is connected to the sheath of index k at the point, wherein said connection device comprises at least one single-wire winding of P turns arranged on the same magnetic core links, a bottom point of said bottom element D kb of said dipole D k to the sheath of index (k−1) at the point corresponding to the start of the winding in order to provide the broadband impedance matching and the power supply for the dipole D k .
