Subwavelength, Compact, Resonant Patch Antennas Loaded With Metamaterials

  title={Subwavelength, Compact, Resonant Patch Antennas Loaded With Metamaterials},

We analyze the matching and radiation properties of subwavelength resonant patch antennas filled with double-negative, double-positive, and/or single-negative metamaterial blocks. Analyzing the theoretical limits inherently present when loading such common radiators with metamaterials, we show how these configurations may exhibit in principle an arbitrarily low resonant frequency for a fixed dimension, but they may not necessarily radiate efficiently when their size is electrically small… CONTINUE READING
