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 1/18λ0× 1/18λ0× 1/19λ0, where λ0 is the free space wavelength at 2.37 GHz.

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 |φ1|, |φ2|≦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： An apparatus based on composite right-handed or left-handed (CRLH) principles to provide a transmission line or antenna structure having a plurality of cells to which one or more feed ports are attached. The apparatus is based on an equivalent circuit Right-Hand (RH) series induction (LR) and shunt capacitor (CR), and Left-Hand (LH) series capacitor (CL) and induction (LL), in which effective permittivity (e) and permeability (m) of the structure are manipulated by the choice of CR, LR, CL, and LL. One embodiment describes mushroom antenna cells (1D or 2D array) in which vias extend up from a feed network on a ground plane through at least one dielectric region to each of a first plurality of conductive elements (plates or strips). Optionally, a second plurality of conductive elements are disposed between first and second dielectric layers to form metal-insulator-metal (MIM) capacitors to lower resonance frequency.
