You likely have one or more on you right now\, under the plastic cover of your cellphone or smartwatch. Cars now bristle with antennas …. AM/FM radio\, GPS navigation\, tire pressur e monitoring …. And new driver support technology is being added regular ly. Some homes still use TV antennas … and don’t forget those satellit e dish antennas proliferating on rooftops.\n\nAntennas provide a specific service – to insert information into the environment and extract it some distance away. Antennas provide the pure realization of Action at a Dista nce.\n\nMany complex systems require the signals to be accurately pointed in a specific direction\, even moving to follow a changing situation. Air traffic control\, military combat\, and space exploration put incredible r equirements on their antennas. We all watch the news and ask “How do the y do that?” This presentation is an attempt to provide some understandin g.\n\nThe antennas used in such service are mind-bogglingly complicated\, but we will break them down into digestible bite-size-chunks so we can lea rn their fascinating stories.\n\nPart 1 described antenna arrays that prec isely aim their signals though mechanical movement or switching between ra diating elements. Part 2 discusses antenna arrays that remain mechanically stationary\, while the signal directionality is precisely controlled by a dding a specific phase shift to each radiating element.\n\nSpeaker(s): Ed Gellender\n\nAgenda: \n7:00 PM Networking\n\n7:30 PM Presentation\n\nVirtu al: https://events.vtools.ieee.org/m/399620 LOCATION:Virtual: https://events.vtools.ieee.org/m/399620 ORGANIZER:EarlyElectronics@ix.netcom.com SEQUENCE:43 SUMMARY:Fascinating Antennas for Complicated Systems\, Part 2 URL;VALUE=URI:https://events.vtools.ieee.org/m/399620 X-ALT-DESC:Description: <br /><p style="font-weight: 400\;">We see antennas everywhere.&nbsp\; You likely have one or more on you right now\, under t he plastic cover of your cellphone or smartwatch.
