This paper presents a 61 GHz narrow-band filter, implemented with Groove Gap Waveguide (GGW) coupled resonators. This structure does not require metal contact on the side walls and, therefore, is very suitable for mm-wave applications. At these frequencies, the manufacturing process imperfections become important, and an appreciable response deterioration can be found using classical microwave waveguides, such as the rectangular waveguide. The presented filter is a 5 pole Chebyshev filter… CONTINUE READING
