Millimeter-wave bandpass filters technologies

This paper presents a review of our recently developed techniques for the design and implementation of the millimeter-wave (mmW) bandpass filter. These filters exhibit many attractive features, including low insertion loss, high inband selectivity, high out-of-band rejection, easy design. Noteworthy that these mmW filters are designed on planar transmission line technology, e.g. microstrip-line, substrate integrated waveguide (SIW).
