Triangular patch resonators have important applications in microwave filters and antennas design. In this report, new isosceles right-angled triangular patch resonator bandpass filters with two-path coupling are developed to perform dual-passband, low passband insertion loss and miniaturization, and performances of the proposed filters are compared. New dual-band bandpass filter using single right-angled...
Rectangular patch resonator is analyzed, and dual-mode and multi-mode bandstop filters using square loop resonator are proposed. Compared with traditional dual-mode filter with single operation band, the new design takes fully advantage of the dominant mode and its degenerate mode, even higher order mode to implement operation band, respectively, and tri-band bandstop filters are developed by using...
