Design and Optimization of Butterworth and Elliptic Band Pass Filters in 5G Application

Filters are two-port networks that may pass or attenuate frequencies within defined ranges and can alter the frequency response of any system. In present research study, goals optimization controller embedded with (ADS2019) used to design Butterworth Elliptic bandpass filters (18GHz – 38GHz), a bandwidth (7GHz), stopband attenuation (S21=-60dB), passband (S21=-1dB). Three types each filter (Hp-Lp 6th order 3rd order) simulated optimized choose best (C, L) values. The selected redesigned using Design Filter Guide, simulation during this phase yields different values for L). designed circuit is then transformed into microstrip model transmission lines open short circuits. study investigates differences between in BW-f center- at stopband.In last line obtain (W, component filter. Finally, compares past studies projects field.
