Choosing Dielectric or Magnetic Material to Optimize the Bandwidth of Miniaturized Resonant Antennas
arXiv:0907.2132 · doi:10.1109/TAP.2011.2164170
Abstract
We address the question of the optimal choice of loading material for antenna miniaturization. A new approach to identify the optimal loading material, dielectric or magnetic, is presented for resonant antennas. Instead of equivalent resonance circuits or transmission-line models, we use the analysis of radiation to identify the fields contributing mostly to the stored energy. This helps to determine the beneficial material type. The formulated principle is qualitatively illustrated using three antenna types. Guidelines for different antenna types are presented.
