摘要: A compact triple-band high-temperature superconducting (HTS) bandpass filter using multimode stub-loaded resonator is proposed in this paper. The resonant characteristics of the are investigated by even/odd-mode analysis. To sharpen passband skirts, a source-load coupling configuration with nonresonant node arranged to produce several extra transmission zeros for realizing high-selectivity performances. For demonstration purposes, operating at 2.45 GHz (ISM band), 3.5 (WiMAX and 5.2 (WLAN band) designed, fabricated, measured. Measurements good agreement electromagnetic simulations. measured minimum insertion losses HTS 0.16, 0.55, 0.22 dB, whereas return greater than 16.7, 10.2, 17.5 respectively. Its overall size only 8.3 mm $\times$ 8.6 mm.
