Herein, radiowave/microwave bandpass/reject filters are fabricated from the tungsten doped Bi_1.5Zn_0.92Nb_1.5‐6x/5W_xO_6.92 (W‐BZN) pyrochlore ceramics. The W‐BZN band filters are prepared by the solid state reaction technique and subjected to X‐ray diffraction (XRD) and impedance spectroscopy analyses. It was shown that the W‐BZN filters can display negative capacitance effects accompanied with resonance‐antiresonance oscillations. The calculations of the reflection coefficient parameter (S₁₁), the return loss (L_r) and the voltage standing wave ratios (VSWR) in the frequency domain of 0.01 to 1.80 GHz, has shown that the W‐BZN device can perform as microwave cavities at two notch frequency values of 0.44 and 1.53 GHz. W‐BZN devices can also be nominated as noise reducers and radiowave/microwave signal receivers suitable for telecommunication technology.

掺杂钨的Bi1.5Zn0.92Nb1.5O6.92陶瓷设计为无线电/微波带通/抑制滤波器

在这里，无线电/微波带通/抑制滤波器是由掺钨的Bi _1.5 Zn _0.92 Nb _{1.5-6 x / 5} W _x O _6.92（W-BZN）烧绿石陶瓷制成的。W-BZN带通滤波器是通过固态反应技术制备的，并经过X射线衍射（XRD）和阻抗谱分析。结果表明，W-BZN滤波器可显示负电容效应，并伴有谐振-反谐振振荡。反射系数参数（S ₁₁），回波损耗（L _r）和电压驻波比（VSWR）的计算）在0.01至1.80 GHz的频域中，表明W‐BZN器件可以在0.44和1.53 GHz的两个陷波频率值下充当微波腔。W‐BZN设备也可以被提名为适用于电信技术的降噪器和无线电波/微波信号接收器。
