Title:
ARRANGEMENT OF ANTENNA STRUCTURES FOR SATELLITE TELECOMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2015/079037
Kind Code:
A3
Abstract:
The invention relates to an arrangement (200) of antenna structures (10) for telecommunications, in particular by satellite, characterised in that each antenna structure (10) includes a transmission-reception surface (14) comprising an axis of symmetry and at least one dipole antenna (12) having a helical shape and sized such as to transmit and/or receive at least one electromagnetic wave having a frequency higher than 4 GHz, preferably 4 GHz to 50 GHz, in particular in a spectral band selected among the X band and the Ku band, and in that at least two axes of symmetry are concurrent.
