Performance Analysis of Fractional-Order Microwave Bandpass Filter for 5G Applications

Abstract

This paper, initially investigates a fractional-order bandpass filter using resistors and inductors. Where, it has been found out that, by incorporation of fractional-order devices in place of classical components, the centre-frequency and bandwidth of the filter can be increased to a very high extend, i.e., to microwave range. Now, in this study, a resistorless bandpass filter has been designed and the orders of the two fractional-inductors L1 & L2 and two fractional-capacitors C1& C2 are varied from 0.3 to 1.0 one at a time. It has been found that the exponents of the elements L1 and C2 play a vital role in improving the fractional bandpass filter’s bandwidth, as well as it increases the frequency range of the filter to 1010Hz to 1025Hz ranges that are probable frequency ranges that can be used for 5G applications.
