Polarization Characteristics of Multiband Loaded Microstrip Annular Ring Antennas

11 mode of the ring, spaced on the frequency spectrum. These multiple modes are excited, when the loading is symmetric on one side of the ring along one axis, and the excitation is off-centered on another side, or vice-versa

  • 11 mode of the ring, spaced on the frequency spectrum. These multiple modes are excited, when the loading is symmetric on one side of the ring along one axis, and the excitation is off-centered on another side, or vice-versa
  • One of the loaded mode frequencies is much lower than the dominant TM 11 mode frequency of the annular ring, indicating a miniaturization of antenna to a great extent
  • Simulation results are confirmed by measurements." /> 11 mode of the ring, spaced on the frequency spectrum
