A two-pole, half-mode substrate-integrated-waveguide (HMSIW) RF MEMS tunable filter with 28% tuning range around 1.4 GHz is presented. The filter occupies a total area of λg × 0.7λg @ 1.4 GHz and exhibits an insertion loss of 1.2-3.4 dB, return loss better than 11 dB and quality factor of 75-140 for all tuning states, while having excellent linearity.
