“…In comparison to [16], a very similar tuning range is achieved while the insertion loss differs slightly. It is evident that, while the proposed filter operates at a much higher frequency than the filters in [4, 14, 15], and is of a higher order than all of the filters compared in Table 4, the tuning range and insertion loss are competitive with recently published works.…”

“…In comparison to the tunable planar resonator filters in [4, 14–16], the tunable filter presented here has the advantage of using the least amount of components per tuning element for the biasing structure. In comparison with the data presented in [17] on the performance of reported tunable filters, the filter presented here has a larger insertion loss and a wider bandwidth, but is similar in tuning range.…”

“…Implemented in the ground planes of the transmission lines, DGS offers substantial flexibility in integration with other technologies and simple fabrication processes. Spiral-shaped resonating structures are featured by its steep band-rejection characteristics, low insertion loss, and exceptional compactness [1], [2]. When the spiral topology is implemented as DGS, multiple harmonics occur at integer numbers of resonant frequency when three or more spiral turns are adopted [3]- [5].…”
