(54) 6-8.5 GHz antenna diplexer with two-level resonating cavities.


(57) 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.
