Abstract (en)

[origin: EP2015390A2] A 6-8.5 GHz antenna diplexer comprises a central-symmetry body having resonating cavities arranged on two levels to reduce the size of the construction and to also exploit the vertical dimension. Thus, the diplexer exploits to a maximum degree all the available volume and, the resonating cavity number and electric features being the same, allows to reduce the overall volume with respect to a conventional diplexer having resonating cavity arranged at a single level.
