Abstract

We significantly diminish the interference between the radiating elements for a miniature MIMO antenna system on the basis of composite right- and left-handed transmissionline(CRLH-TL). The element radiating structure has capacitively coupled parallel metal parts and slotted ground that correspond to the CRLH-TL to prohibit the volume from growing for an LTE high band. The metal line suspended over the radiating elements is optimally designed to drop the unwanted mutual coupling to -23 dB, as the entire MIMO antenna structure is small and it performs electrically useful. The test case is done for 2.5 GHz.
