Resonant frequency calculation of meander dipole antennas by TLM

A new method for calculating the resonance frequency of an arbitrary meander dipole antenna (MDA) is proposed by making use of a full transmission line model approach. Once the current distribution of MDA is analyzed, a theoretical formula is obtained for input voltage and resonance frequency calculation. The model is compared with simulations and prototype measurements on three MDA families: those which exhibit an increasing number of meanders, variable meander sizes, and locations within MDA, respectively. The error is below 7.8% in all cases. Conclusions are drawn on optimal meanders for miniaturization. © 2008 Wiley Periodicals, Inc.
