Abstract

This paper presents a ground-breaking triple-bandpass filter design utilizing a modified T-shape rectangular coupled with a stepped impedance resonator (MTSR-CSIR) for smart portable communication device applications. The MTSR-CSIR filter operates at (2.2, 3.62 and 4.6) GHz, providing wide passbands in three operating modes. To achieve the optimal performance, the filter design is executed on a multi-layered liquid-crystal polymer (LCP) substrate with a thickness of 50 µm, dielectric constant of 2.9 and loss tangent of 0.002. Simulation results for the MTSR-CSIR filter demonstrate a high level of accuracy and consistency with the measurement results for the fabricated filter. The filter exhibits an excellent stopband rejection, low loss and compact size while maintaining high-performance levels. Its performance parameters, such as insertion loss, return loss and group delay, are considered to evaluate the filter’s performance. The results highlight the applicability of the MTSR-CSIR filter for smart portable communication devices.

采用改进的t形矩形耦合阶跃阻抗谐振器设计用于智能便携式通信设备的三带通滤波器

本文提出了一种突破性的三带通滤波器设计，利用改进的t形矩形与阶跃阻抗谐振器(MTSR-CSIR)耦合，用于智能便携式通信设备应用。MTSR-CSIR滤波器工作在(2.2,3.62和4.6)GHz，在三种工作模式下提供宽频带。为了获得最佳性能，滤波器设计在多层液晶聚合物(LCP)衬底上进行，衬底厚度为50µm，介电常数为2.9，损耗正切为0.002。对MTSR-CSIR滤波器的仿真结果表明，该滤波器具有较高的精度，且与预制滤波器的测量结果一致。该滤波器具有优异的阻带抑制，低损耗和紧凑的尺寸，同时保持高性能水平。考虑了插入损耗、回波损耗和群延迟等性能参数来评价滤波器的性能。结果表明MTSR-CSIR滤波器适用于智能便携式通信设备。
