Iyer\nUniversity of Alberta\n\n20 July 2026\nSDSU EIS-320 Conference R oom\n1500 - 1600\n\nAttendance of 11 including speaker.\n\nDr. Satish Shar ma (SDSU\, and the organizer of the talk) introduced Dr. Iyer\, describing his successful lab and shared connections with warmth and enthusiasm.\n\n Dr. Iyer is fortunate to have the room to broadly explore antenna design t opics in miniaturized microwave antennas. It was clearly evident from the presentation that his leadership is making an ongoing and enduring impact. \n\nThe talk covered many of the projects under consideration in his resea rch group at the University of Alberta\, located in Edmonton\, the capital of the province. Located east of the Rockies\, Edmonton is the most north ern city in Canada with population of more than a million people and it se rves as Canada's primary logistical interface to the Arctic and boasts the continent's largest stretch of continuous urban parkland. Research suppor ting tactical operations in the Arctic was a thread woven throughout the p resentation.\n\nThe University of Alberta has over 46\,000 students distri buted among 18 faculties and generates 600 million in sponsored research r evenue per year. It has a major open-access nanoFAB\, which is free for us e by students and open to industry to use as well. The ECE department has 60 faculty and is one of the largest ECE departments in Canada.\n\nAfter t his brief introduction\, we had a pop quiz! Dr. Iyer showed two photos of people and asked "Who are they?" They were the bachelor's graduation photo s of George Sinclair\, and Edward Jordan. George studied slot arrays\, rad ar scattering\, scale modeling. Edward researched antennas and radar\, but is recognized for significant contributions to antenna education. Both we re affected by their PhD advisor being absorbed by the US Signal Corps dur ing WWII.\n\nThese two engineering researchers were pioneers in Canada\, e stablishing antenna labs and attracting lots of researchers. Classical ant enna science moved forward due to their efforts\, and both Dr. Sharma and Dr. Iyer have connections their work.\n\nThe primary research theme of the lab is very low profile\, weight\, power\, and cost antennas and microwav e devices. "Low SWaPC" The lab focus includes the synthesis and modeling o f denied EM environments. Antennas\, sensors\, meta-material devices for G PA\, GPR\, wires communications\, security defense\, and oil and gas are a ll considered. Defense work is a large part of the lab focus.\n\nThis mean s that the research concerns lots of sensors\, antenna platforms\, integra ted platforms\, zero-power biometric sensing\, ad-hoc networks\, meta-surf aces\, signature management\, and radar cross section. The lab partners wi th a variety of companies and organizations that those of us in the San Di ego Section would be very familiar with.\n\nThe motivation is to innovate and refine electrically small antennas\, meta-material-based antennas\, an d small antennas.\n\nChallenges? There are clear challenges to this type o f work. There are fundamental limits on bandwidth\, quality factor\, and g ain. Matching impedances to the components and the environment is one of t he most difficult challenges for very small antenna designs.\n\nIn order t o get power radiated from even a very small antenna\, you need a matching network. That matching network might be very bulky compared to the miniatu rized antenna. If you do manage to get power into the antenna\, the bandwi dth ends up being small\, because of losses exacerbated in the antenna. Sm all structures are difficult. Radiation efficiency is strongly reduced.\n\ nDr. Iyer introduced an "Inherently Matched" electrically small folded dip ole. Usually a half wavelength is the operating size/length of a dipole an tenna. The resonance point was clearly shown on an impedance vs. length gr aph. Moving the resonance down\, so that we get a smaller length\, is the goal.\n\nWe reviewed inherent matching technique for Frequency Division Du plex Electrically Small Antennas (FDD ESAs). Dr. Iyer explained that the p rinted folded dipole with lumped L and C loading was used with positive re sults. This is a miniaturized planar folded dipole.\n\nRoom: 320\, Bldg: E IS\, SDSU\, San Diego\, California\, United States LOCATION:Room: 320\, Bldg: EIS\, SDSU\, San Diego\, California\, United Sta tes ORGANIZER:w5nyv@yahoo.com SEQUENCE:5 SUMMARY:In Pursuit of Low-Cost\, Multifunctional\, and Electrical Small Ant ennas for Microwave and Millimeter-Wave Communications URL;VALUE=URI:https://events.vtools.ieee.org/m/569086 X-ALT-DESC:Description: <br /><p>In Pursuit of Low-Cost\, Multifunctional\, and Electrical Small Antennas for Microwave and Millimeter-Wave Communica tions</p>\n<p>Prof. Ashwin K.
