Configurable multiband antenna arrangement with wideband capacity and design method thereof
Système d'antenne multibande configurable à capacité de large bande et son procédé de conception
Résumé
The invention discloses an antenna arrangement of a bonsai type, where not only the resonating frequencies may be adjusted, but also the bandwidth around some or all resonating frequencies. This is achieved by adding new branches to the trunk of the bonsai antenna arrangement. The positions and lengths of the branches are defined as a function of the frequencies around which the bandwidth should be adjusted. The antenna arrangement may be inscribed in a 3D compact volume of a specific form factor. It may also be inscribed in a planar structure. The antenna arrangement may be produced at a low cost. It may be used in a variety of applications, including communications in WiFi or other standards of multimedia content that need defined bandwidths for instance to comply to a predetermined quality of service.
