Abstract

ABSTRACT A novel substrate-integrated low-temperature ceramic co-fired (LTCC) millimeter-wave bandpass filter operating in the Ka-band is proposed. The filter is composed of multiple layers of media and metal plane. The dielectric resonators (DRs) with high dielectric constant are embedded in LTCC dielectric cavity excavated in LTCC dielectric. The input/output (I/O) is exploited by the slot on metal plane feed by CPW （Co-Planar Waveguide）structure on the top and bottom metal planes, which make the filter able to be integrated to the other components. Simulations and measurements show that the filter has a center frequency of 35 GHz, a relative bandwidth of about 6%, an insertion loss of 1.25 dB, and a return loss of −15 dB in the passband. The filter has many advantages, such as high selectivity, wide bandwidth, low profile, small volume, and so on, which has high engineering application in 5G communications.

紧凑型LTCC毫米波带通滤波器，内置介电谐振器

摘要提出了一种新型的工作在Ka波段的衬底集成低温陶瓷共烧（LTCC）毫米波带通滤波器。过滤器由多层介质和金属平面组成。具有高介电常数的介质谐振器（DR）嵌入在LTCC介质中挖掘的LTCC介质腔中。输入/输出（I/O）由顶部和底部金属平面上的CPW（共面波导）结构的金属平面上槽馈电来利用，这使得滤波器能够集成到其他组件。模拟和测量表明，该滤波器的中心频率为35GHz，相对带宽约为6%，插入损耗为1.25dB，通带回波损耗为-15dB。该滤波器具有选择性高、带宽宽、低剖面、体积小等优点，在5G通信中具有较高的工程应用价值。
