摘要： A compact multi-band hybrid ring (rat-race) coupler utilizing a ring of composite right-handed and left-handed (CRLH) transmission lines (TLs) and multiple ports, provides miniaturization and the ability to operate at arbitrary frequency bands unlike conventional couplers. The hybrid ring is made compact, such as by constraining phase delay contributions | ϕ 1 |, | ϕ 2 | ≤ 270°. The coupler can be used in many applications, for example as a mode decoupling network in a dual-band front-end MIMO system. The inclusion of a CRLH delay line is also described which alters the phase relationship of the signals and is particularly well suited for extending pattern diversity in response to frequency.

摘要： 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.
