    • A dual-band resonator with compact size, such as a resonant type dual-band antenna, which uses an anisotropic metamaterial is described. The artificial anisotropic medium is implemented by employing a composite right/left-handed transmission line. The dispersion relation and the antenna physical size only depend on the composition of the unit cell and the number of cells used. By engineering the characteristics of the unit cells to be different in two orthogonal directions, the corresponding propagation constants can be controlled, thus enabling dual-band antenna resonances. In addition, the antenna dimensions can be markedly minimized by maximally reducing the unit cell size. A dual-band antenna is also described which is designed for operation at frequencies for PCS/Bluetooth applications, and which has a physical size of 1/18λ 0 x 1/18λ 0 x 1/19λ 0 , where λ 0 is the free space wavelength at 2.37 GHz.
    • 描述了使用各向异性超材料的具有紧凑尺寸的双频带谐振器,诸如谐振型双频带天线。 人造各向异性介质通过采用复合右/左手传输线来实现。 色散关系和天线物理尺寸仅取决于单位单元的组成和所用单元的数量。 通过将单位单元的特性设计为在两个正交方向上不同,可以控制相应的传播常数,从而实现双频带天线共振。 另外,通过最大限度地减小单位单元尺寸,可以使天线尺寸显着最小化。 还描述了一种双频天线,其被设计用于在PCS /蓝牙应用的频率下操作,并且其物理尺寸为1 /18λ x 1 /18λ 0 x 1 /19λ<0>,其中λ<0>是在2.37GHz处的自由空间波长。
