Compact Segmented-Coupled Loop Antennas with the Metamaterial Zeroth-Order-Resonance Magnetic-Field Distribution for Higher Antenna-Integration and Lower Interference, and Array Structures.

摘要

The present invention provides a small-size MNG zero-order antenna of which individual radiator elements have excellent performance. When multiple small-size MNG zero-order antennas are arranged, the interference between adjacent elements is smaller than 0.25 wavelengths and the capacity and maximum transmission speed of a MIMO system can be met. According to the present invention, the technical point of the MNG zero-order antenna is that an RH strip including a right-hand transmission feature only is formed in a partial section of a loop antenna, and an inner parallel coupling line and an outer parallel coupling line which are coupled in parallel at a certain distance from the RH strip are included on the inner side and the outer side of the RH strip. By doing so, the interference between radiator elements can be minimized and the original individual radiation features can be guaranteed to the maximum. Furthermore, a technical benefit of providing an antenna for MIMO communications capable of improving the system capacity and the maximum speed is expected.
