摘要
基片集成波导结构具有低插损、高集成、高功率容量等特性,在微波毫米波频段获得广泛应用。本文提出一种毫米波双层基片集成波导带通滤波器,采用双层四腔交叉耦合结构,有效减小尺寸,并引入一对传输零点,提高了带外抑制。根据耦合矩阵来调节腔间耦合强弱,进而得到滤波器物理尺寸。该滤波器中心频率为25.6GHz,带宽为3GHz,带外传输零点22.1GHz与31.3GHz,尺寸为11.6mm*8.2mm。满足5G毫米波频段的通信需求。
Substrate integrated waveguide(SIW) has the characteristics of low insertion loss, high integration, high power capacity and so on, which is widely used in the microwave and millimeter wave communication systems. In this paper, a millimeter wave bandpass filter based on dual-layer substrate integrated waveguide is proposed, and the four cavities cross-coupled structure is adopted, which can effectively reduce the size and introduce a pair of transmission zeros. The coupling strength is adjusted according to the coupling matrix, so as the physical size is obtained. Results indicated that the center frequency of the filter is 25.6GHz, and the bandwidth is 3GHz, the transmission zeros located at 22.1GHz and 31.3GHz, respectively. The size is 11.6mm*8.2mm, which meets the design requirements of 5G communication well.
