Patch antennas partially loaded with a dispersive backward-wave material

  title={Patch antennas partially loaded with a dispersive backward-wave material},
  author={M. E. Ermutlu and Sergei Tretyakov},
  journal={2005 IEEE Antennas and Propagation Society International Symposium},
In this work a transmission-line model for a patch antenna where a half of the patch is loaded with a dispersive material with negative parameters is used to explore the antenna bandwidth characteristics. Possibilities to reduce the antenna size using the phase compensation in the loaded patch are considered. Resonant properties of patch antennas loaded with a dispersive material and with a non-dispersive medium having ε<inf>0</inf>=-ε<inf>o</inf>, μ<inf>0</inf>=-μ<inf>0</inf>are compared with… CONTINUE READING
