MULTI-BAND ACTIVE INTEGRATED MIMO ANTENNAS

摘要

The multi-band active integrated MIMO antenna is a planar structure that includes active devices such as power amplifiers (PA) for transmit modes, as well as low-noise-amplifiers (LNA) for receive modes or complete transceivers (both PA and LNA for bi-directional operation, i.e. transmit and receive modes simultaneously). The antenna provides active loading to facilitate a diversity advantage expected from 4G and 5G wireless systems. The integrated active amplifier device within the antenna increases system throughput while supporting multi-band operation for multi-wireless standards. Moreover, integration with the radio frequency front end eases matching while providing higher gain.

1. A multi-band active integrated (MAI) MIMO antenna, comprising:
a planar substrate which includes a top face and a bottom face; at least one multi-band antenna printed in a MIMO configuration on the top face of the planar substrate; at least one active element operably connected to the at least one printed multi-band antenna and loading the at least one printed multi-band antenna, the at least one active element, being disposed on the top face of the planar substrate and proximate to the at least one printed multi-band antenna; and a biasing network connected to the at least one active element, the biasing network being disposed on the top face of the planar substrate.
