Design of narrow band-pass planar filters for millimeter-wave applications up to 220 GHz
Résumé
This paper deals with the design of passive band-pass filters in thin film microstrip (TFMS) technology for millimeter-wave application in G-band frequency range. The filters to be designed are realized on a BCB-based technology. Quality of the design method as well as technological process has already been fully tested in W-band at 94-GHz. Thus, transposition to higher frequency is investigated at 180 GHz. In such a frequency range, designers are faced to technological point locks. So as to overcome them, specific design techniques are discussed for several filter realization
