All IEEE/IET members and guests are welcome to attend\, but you must register in advance per the we binar link below.\n\nIn addition to our speakers shown below\, we are hono red to have Zhong Chen\, Director of RF Engineering with ETS-Lindgren and past Distinguished Lecturer with the IEEE EMC Society\, present: Extending the Usable Low Frequency Range of an Anechoic Chamber for Antenna Calibra tions Using a Time Domain Deconvolution Filter. Abstract: It is usually im practical to calibrate antennas in an anechoic chamber down to the VHF fre quency range\, because absorbers do not perform adequately at these freque ncies. Time domain gating can be used to the extent that the antenna ring- down time is short enough\, and the reflections are far enough away\, so t hat a gate can be applied without cutting into the antenna intrinsic respo nse. Although it could be possible to apply time domain gating at a closer distance in many chambers\, it is typically not feasible to do so in the far field where the path lengths of the reflected signals are too close to that of the direct signal. In this study\, we investigate calibrating bro adband biconical antennas from 75 MHz to 2 GHz in a chamber designed for a bove 1 GHz measurements (in which the absorbers have severely degraded per formance in the VHF frequency range\, and chamber walls are too close to b e gated out directly) using time domain deconvolution filter before a gate is applied. After applying the deconvolution filter acquired from a 3 m m easurement in the same chamber\, we successfully obtained the free space r esponse at a far field distance (e.g.\, 8 or 9 m) for biconical antennas o perating from 75 MHz to 2 GHz.\n\nWe are also excited to have the Chair of the IEEE EMC Seattle Chapter\, Dennis Lewis with The Boeing Company\, as our webinar host and moderator. Dennis received his BSEE degree with hono rs from Henry Cogswell College and his MS degree in Physics from the Unive rsity of Washington. He has worked at Boeing for 32 years and is recognize d as a Technical Fellow\, leading the enterprise antenna measurement capab ility for Boeing Test and Evaluation. He currently has leadership and tech nical responsibility for the primary RF\, Microwave\, and Antenna Metrolog y labs. Dennis holds 10 patents and is the recipient of the 2013 and 2015 Boeing Special Invention Award. He is a member of the IEEE and several of its technical societies including the Microwave Theory and Techniques Soci ety (MTT-S)\, the Antennas and Propagation Society and the Electromagnetic Compatibility (EMC) Society. He serves as a Board Member and is a past Di stinguished Lecturer for the EMC Society. He is a Senior Member\, served a s Vice President on the Board of Directors for the Antenna Measurements Te chniques Association (AMTA)\, and chaired its annual symposium in 2012. De nnis is a part time faculty member teaching a course on Measurement Scienc e at North Seattle College and is chair of the Technical Advisory Committe e. His current technical interests include aerospace applications of rever beration chamber test techniques as well as microwave measurement systems and uncertainties.\n\nCo-sponsored by: / Supported by the Institution of E ngineering and Technology (IET)\n\nSpeaker(s): Professor Stuart Gregson\, Mr. Jason Bommer\n\nAgenda: \n8:00 am PST Welcome and Announcements – M r.
