  • Bandpass filter using triangular patch resonators
    Patent number: 11289789
    Abstract: A six-pole patch bandpass filter includes a dielectric substrate and six electrically-conductive isosceles-triangle patches disposed thereon. A first pair of the patches is an electrically connected pair. The first pair of patches is capacitively coupled to a first microstrip. A second pair of the patches is also an electrically connected pair. The second pair of patches is capacitively coupled to a second microstrip. A third pair of the patches are nested between and capacitively coupled to the first pair of patches and the second pair of patches.
