Herein, zinc phthalocyanine (ZnPc) layers are used as an active material to fabricated radiowave/microwave band filters. The thin layers of ZnPc are coated onto Au and Mn thin‐film substrates to form ohmic and Schottky interfaces, respectively. The Au/ZnPc and Mn/ZnPc devices are structurally and electrically characterized by means of X‐ray diffraction and impedance spectroscopy techniques in the frequency domain of 0.01–1.80 GHz, respectively. The structural investigations show that both interfaces exhibit strained structures of the monoclinic phase of ZnPc. It is also observed that while the Au/ZnPc/Ag devices display negative capacitance (NC) effects in the microwave region above 1.46 GHz, the Mn/ZnPc/Ag devices show resonance–antiresonance capacitive response in the radiowave region accompanied with NC effects in the range of 0.06–1.80 GHz. In addition, analyses of the reflection coefficient spectra have shown the ability of the (Mn, Au)/ZnPc/Ag interfaces to behave as a typical high‐/low‐bandpass filters. The filters can be operated in microwaves and radiowave ranges. The return loss spectral investigations on these filters have shown their ability to reach the market standards.

（Au，Mn）/ ZnPc / Ag界面作为无线电波/微波带滤光片的制造
在此，将酞菁锌（ZnPc）层用作制造的无线电波/微波带滤光片的活性材料。ZnPc薄层涂覆在Au和Mn薄膜基板上，分别形成欧姆和肖特基界面。Au / ZnPc和Mn / ZnPc器件分别通过X射线衍射和阻抗谱技术在0.01–1.80 GHz的频域上进行结构和电气表征。结构研究表明，两个界面均表现出ZnPc单斜晶相的应变结构。还可以观察到，虽然Au / ZnPc / Ag器件在1.46 GHz以上的微波区域显示负电容（NC）效应，但Mn / ZnPc / Ag器件在无线电波区域显示共振-反共振电容响应，并伴随着NC效应。范围为0.06-1.80 GHz。此外，对反射系数光谱的分析表明，（Mn，Au）/ ZnPc / Ag界面具有作为典型的高/低带通滤波器的能力。过滤器可以在微波和无线电波范围内工作。对这些滤波器的回波损耗频谱研究表明它们具有达到市场标准的能力。
