Abstract :
In this paper design and implementation of a narrowband electronically tunable micro-strip comb-line filter with wide tuning range in S-band is presented. This filter is constructed in substrate micro-strip with relative dielectric constant of 10.2, with less than 2% bandwidth at 2.8 GHz center frequency and a wide tuning range from 2.45 to 3.15 GHz with low ripple over tuning range. Narrow bandwidth, remarkable shape factor, low degradation in pass-band over tuning range and symmetrical insertion loss of filter are considerable characteristics of overall response
