PROJECT TITLE :
A Compact MIMO Antenna using CRLH Configuration Double-Layered Folded Ring Radiations with Planar Mushroom Decoupling Structure
??????This paper proposes a unique compact multiple-input??multiple-output (MIMO) antenna, which has miniaturized radiators
and improved isolation, working for the long-term evolution (LTE) mobile communication. Every of the proposed
radiators includes a double-layered ring of the composite right- and left-handed transmission-line configuration, which
has the footprint of thirty by 30, much smaller than the traditional MIMO antenna radiators. These radiators
will be placed shut to each other and have a planar modified mushroom structure between them for the next isolationthirteen; level. The design starts from the equivalent circuit for the LTE 1.seven-GHz-band antenna, finds a physical structure
suitable for the circuit, and is verified by comparing the circuit simulation with the three-D EM simulation and measured
data. The dispersion diagram shows that the zeroth-order resonance coincides with the middle frequency of thethirteen; band, and therefore the fabricated antenna has the come loss less than -10 dB, the isolation over twelve dB, and the radiationthirteen; efficiency over fifty%.
