摘要: Implementation of a novel high gain miniaturized radio repeater for improving wireless network connectivity in complex environment is presented this paper. Unlike existing systems, system utilizes two closely spaced low profile planar antennas capable producing omnidirectional and vertical radiation pattern as well channel isolator layer that serves to decouple the adjacent antennas. The metamaterial based an electromagnetic shield, thus enabling it be built sub-wavelength size 0.07λ02 × 0.014λ0, smallest ever built. A prototype small fabricated verify design performance through standard free-space measurement setup. feasibility amplifying re-transmitting received signal demonstrated which compares with numerical simulation results.
