Abstract
The paper investigates the resonant frequencies of helical resonators. Full-wave 3D electromagnetic analysis is used to verify closed-form formulas known from literature. Corrections to formulas for dominant mode and new formulas for higher modes are proposed. Two-helical resonators filter was designed and measured.
