Design and Performance Analysis of Multi-Band Band Pass Filter Using Meander-Line Resonator

A lot of attention has recently been paid to wireless communication technology. Communication networks have gotten more influential as technology has advanced, especially in the realm of standard microwave/millimetre wave components. The low-frequency circuit has the qualities of stability and high anti-interference performance, and several dual and multi-band BPFs have already been proposed thus far employing a variety of resonators. Due to these resonators the size of the filter increases and automatically the performance of the filter may be decreased because of complexity. To overcome these type of problems, Microstrip filters have been advised which offers a high-level performance. In this paper, we proposed to design and simulate a meander line resonator based multi band tunable filter (BPF) using High-Frequency Structure Simulator (HFSS). This is done in order to maintain a more steady—state operating frequency range and to prevent frequency changes that could result from environmental influences. It is simple to change these multi-band filters from band-pass to band-stop filters.
