WebAbstractIn this paper, a miniaturization technique and atuning concept that enable the realization of highly miniaturizedand frequency reconfigurable helical filters are reported for thefirst time. The proposed filter design is based on tunable helicalresonators with an internal volume of only 8.6 cm and variablecapacitive loading. WebNevertheless the test result is very close to the design target. Some measurements indicate a 3dB bandwidth of about 4MHz.
