Small patch antennas arranged in matrix form are used in millimeter wave wireless devices. These antennas are not detachable from the devices, and the compliance and other characterizing tests must be performed over the air. Measurements in the nearfield are potentially problematic because test data cannot be accurately extrapolated to different distances. Therefore, most measurements must be made in the far-field. For determining the far-field distance, both device and measurement antenna apertures must be considered. While the far-field distance of some measurement antenna can be approximately predicted using conventional methods, there is no known method for determining the smallest far-field formation distance of massive MIMO antenna system. This paper describes a heuristic approach for determining the far-field formation distance of millimeter wave massive MIMO antenna system used in 5G transceivers.
 

Biography:

Steve Majkowski is a member of technical staff of the Global Products Compliance Laboratory at Alcatel-Lucent’s Bell Laboratories in Murray Hill, New Jersey.   Since 1997 he has been responsible for the evaluation, test and certification of new wireless base stations products with the Federal Communication Commission.  He has executed 30 Formal Product Certification filings with the FCC for AWS, Cellular 850 and PCS products and has performed hundreds of product evaluations.  These products form the bulk of the wireless infrastructure for such companies as Verizon and Sprint within the US of A and other wireless service providers in the Americas and internationally.  During this time, he led the development of an automated measurement system and a methodology for the evaluation of medium power (< 5kW) RF transmitters.  Prior to joining Bell Laboratories, He was at Lockheed Martin AstroSpace where he was the EMC Technical Leader for the composite structured A2100 Commercial Satellite Programs Core Spacecraft design.  He personally supervised development and construction of multiple spacecraft including ChinaStar, GE1 through GE5, EchoStar 104, 105 & 106 and the AceS Spacecraft. The Commercial Space projects followed a significant success as the EMC Technical Leader for NASA’s Earth Observing System. Mission to Planet Earth “terra” spacecraft. The $1.7B terra spacecraft was a revolutionary advance in spacecraft technology incorporating a composite structure, 120VDC direct energy DC power systems, high data rate communication systems, a revolutionary hybrid grounding system and the first space based solid state data recorder memory management system.  The terra spacecraft was the most expensive, largest, most powerful, highest data rate, most sensitive and the most electromagnetically quiet spacecraft that NASA had ever launched.  Other previous spacecraft contributions included the International Space Station, GPS Block IIR, Milstar, TIROS, Intelsat and Inmarsat.  Previously the author had spent 10 years in the RF Engineering and Radar group at Lockheed Electronics.  It was there as the Senior Principal Engineer for EMC and High Power RF design that he was involved in the development of components, antennas and systems for multiple programs including the Space Shuttle, B2 Bomber, Trident C4/D5, Aegis, Hubble, C5 Galaxy, B52, F15, F16, F22 and other classified programs. Mr. Majkowski received his BSEE from New Jersey Institute of Technology in 1979 and performed Graduate studies at Stevens Institute, NJIT and George Washington University.  He is a NARTE Certified EMC Engineer and a member of the IEEE EMC Society.  He has received commendations from the US Navy, the US Air Force and NASA for his work on various programs.
