SUMMARY:Radio Shop Chat: Performance of Antenna-in-package (AiP) Designs at Millimeter Wave Frequencies
DESCRIPTION:NSF SpectrumX invites you to the next Radio Shop Chat\, “Performance of Antenna-in-package (AiP) Designs at Millimeter Wave Frequencies\,” featuring Rashaunda Henderson\, on Wednesday\, July 1 at 3 p.m. ET. \nRegistration is required and free. \nAbstract\nAntenna-in-package (AiP) technology has become an important solution for next generation wireless systems. As the operating frequency of systems increases\, the size of the antennas decreases and to reduce losses\, interconnecting the die to the antenna at the package level has become a viable technique. This research has focused on the electrical and mechanical characterization of packaging substrates and over-mold compounds for antenna-in-package design and reliability. The research effort has culminated in the manufacturing of a slot bowtie antenna and E-shaped patch antenna designed to operate in G band which has frequency limits of 140-220 GHz. The antennas have been designed for characterization using a WR5 rectangular waveguide to package transition to eliminate any radiation that would be caused by a traditional ground-signal-ground (GSG) probe. Antenna input impedance bandwidth and radiation patterns will be presented for both GSG and waveguide fed antennas. In addition\, we will demonstrate the high-frequency properties of two dielectric materials (A and B) used in the fabrication process of a flip-chip enhanced quad flat no-leads package (FCeQFN) using free-space quasi-optical spectrometer (FSQS) technique. The materials are Ajinomoto Build-up Film-based laminates that drive the FCeQFN technology. Material A and B show an average dielectric constant of 3.33 and 3.45\, respectively\, with an average loss tangent of 0.01 across the G band. \nSpeaker Bio\nRashaunda Henderson is a professor in the ECE department at the University of Texas at Dallas in Richardson\, TX. She received her B.S degree in electrical engineering from Tuskegee University in 1992 and her M.S. and Ph.D. degrees in electrical engineering from the University of Michigan in Ann Arbor\, MI\, in 1994 and 1999\, respectively. She joined Motorola Semiconductor Product Sector in Tempe\, AZ (now NXP Semiconductors) and worked as a research and development device engineer focusing on passive circuit integration in the microwave and mixed-signal technology labs for wireless embedded systems. She joined UT Dallas in 2007 as an Assistant Professor in the Erik Jonsson School of Engineering and Computer Science. Henderson is the co-founder of the High Frequency Circuits and Systems Laboratory\, which facilitates millimeter-wave design and development of circuits\, integrated packages\, and antennas for wireless communication systems. She has co-authored more than 100 journal and conference papers focusing on packaging and integration for high-frequency applications. Henderson is a Senior Member of the IEEE and served as the 2022 President of the IEEE Microwave Theory and Technology Society (MTT-S) Administrative Committee. She is passionate about educating the next generation of students and encouraging them to seek careers in science\, technology\, engineering\, and mathematics.
