abstract

  • This article presents the implementation of three inverted microstrip gap-waveguide (IM-GWG) bandpass filters for the Ka-band, at a central frequency of 28 GHz. This technology is a good candidate for the future communication systems operating in the millimeter-wave frequency bands due to the low loss characteristic and the easy manufacturing due to the increased size for these frequency bands. Three different topologies will be analyzed and their sensitivity to the position with respect to the pins of the bed of nails will be studied. Measurements confirm the good performance of the technology in terms of transmission and reflection coefficients over the whole assessed band.
