Choosing Dielectric or Magnetic Material to Optimize the Bandwidth of Miniaturized Resonant Antennas
Choosing Dielectric or Magnetic Material to Optimize the Bandwidth of Miniaturized Resonant Antennas
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 …
