Merging Antenna and Electronics Boosts Energy and Spectrum Efficiency

By integrating the design of antennas and electronics, researchers from the Georgia Institute of Technology have boosted the energy and spectrum efficiency for a new class of millimeter-wave transmitters, allowing improved modulation and reduced generation of waste heat.

The new co-design technique - achieved through research sponsored by the U.S. Army Research Laboratory and Intel Corp. - allows simultaneous optimization of the millimeter-wave antennas and electronics. The hybrid devices use conventional materials and integrated circuit (IC) technology, meaning no changes would be required to manufacture and package them. The co-design scheme allows fabrication of multiple transmitters and receivers on the same IC chip or the same package, potentially enabling multiple-input-multiple-output (MIMO) systems as well as boosting data rates and link diversity.
