ABSTRACT

This paper presents a reconfigurable loop-based filter performing compound reconfiguration. The designed filter is capable of functioning as a bandstop or bandpass filter by a simple approach of cascading the resonator to the transmission line connecting source and load. Shifting of operating frequencies is characterised by switching between a loop and a C-shaped resonator. To demonstrate the working of the proposed concept, a compound reconfigurable filter operating at 1.5 GHz and 1.6 GHz is developed. The filter is developed on a compact layout of size 0.27 × 0.12 λ_g². The proposed prototype is fabricated and measured for real-time validation.

摘要

本文介绍了一种可重构的基于环路的滤波器，该滤波器执行复合重构。通过将谐振器级联到连接源和负载的传输线的简单方法，设计的滤波器能够用作带阻或带通滤波器。工作频率偏移的特点是在环路和 C 形谐振器之间切换。为了演示所提出概念的工作原理，开发了一种在 1.5 GHz 和 1.6 GHz 下运行的复合可重构滤波器。该滤波器是在尺寸为 0.27 × 0.12 λ _g ²的紧凑布局上开发的。所提出的原型被制造和测量以进行实时验证。
