US Patent Issued to TELEFONAKTIEBOLAGET LM ERICSSON on Dec. 9 for "Advanced antenna system active impedance load mitigation" (Swedish Inventors)

ALEXANDRIA, Va., Dec. 9 -- United States Patent no. 12,494,834, issued on Dec. 9, was assigned to TELEFONAKTIEBOLAGET LM ERICSSON (PUBL) (Stockholm).

"Advanced antenna system active impedance load mitigation" was invented by Magnus Nilsson (Lund, Sweden), Hans Hagberg (Limhamn, Sweden) and Viktor Arfwedson (Uppsala, Sweden).

According to the abstract* released by the U.S. Patent & Trademark Office: "In an Advanced Antenna System, a desired power amplifier, PA, load distribution, which counters the mismatch of active impedance load, is achieved by altering the lengths of routing traces connecting PA outputs and corresponding antenna elements/subarrays. The combined output performance in the beam during active impedance load is then restore...
