Dual-band right-angled triangular resonator bandpass filter

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 triangular patch resonator is also presented, and the experiment demonstrates the design. The new filters are some applications of right-angled triangular patch resonator, and are expected to find applications in future wireless communication systems.
