At these frequencies\, antenna performance becomes critical to overall system reliability and efficiency. Active phased arrays are exp ected to be widely deployed in both base transceiver stations (BTSs) and u ser terminals (UTs). However\, successful implementation is challenged by material uncertainties\, fabrication tolerances\, and interference from su rrounding components.\n\nBTS antennas must meet stringent requirements for sidelobe suppression\, cross-polarization control\, and stable beam squin t performance. Meanwhile\, UTs typically employ antenna-in-package (AiP) d esigns to reduce form factor\, introducing additional complexities related to thermal management\, radiation consistency\, beam steering accuracy\, and calibration—challenges that are common across most mmWave wireless s ystems.\n\nThis lecture offers a comprehensive introduction on antenna des ign and system integration at mmWave frequencies\, with an emphasis on B5G /6G applications. We begin by reviewing system requirements and applicatio n scenarios to contextualize antenna specifications and design choices. Va rious antenna architectures—such as beam-switching and multi-beam arrays —will be introduced\, along with their beamforming principles and associ ated control architectures.\n\nBeyond design considerations\, the lecture also addresses essential system-level issues including heat dissipation st rategies\, RF component testing\, measurement methodologies\, and calibrat ion techniques\, covering both R&D and mass production contexts. This cont ent is intended to equip engineers\, researchers\, and system integrators with the foundational knowledge necessary to develop and deploy high-perfo rmance antenna systems for the next generation of mobile communication net works.\n\nBiography\n\nProfessor Hsi-Tseng Chou (IEEE Fellow’2012) recei ved his B.S. in Electrical Engineering from National Taiwan University (NT U) in 1988 and his M.S. and Ph.D. from The Ohio State University (OSU) in 1993 and 1996\, respectively.

His team is inter nationally recognized for its contributions to asymptotic high-frequency t echniques in real and complex space\, especially in Uniform Geometrical Th eory of Diffraction (UTD)-based ray and beam methods. These solutions have been widely implemented in the design of high-gain antennas such as refle ctors\, reflectarrays\, and phased arrays.\n\nWith over three decades of e xperience\, Professor Chou has led the development of end-to-end RF subsys tems at millimeter-wave frequencies\, integrating RFICs and baseband DSP a lgorithms. He has collaborated with over 60 companies and research institu tes globally\, providing consulting services to more than 16 antenna-relat ed firms and playing a pivotal role in developing Taiwan's antenna industr y ecosystem. His contributions include forming the "High-Gain and Smart An tenna Industrial Technologies Consortium\," nurturing companies in satelli te TV\, microwave links\, and mobile base station antennas—many of which have become global leaders.\n\nHe has spun off two startups from his rese arch teams\, serves on corporate boards\, and mentored several Ph.D. stude nts in founding their own companies. His contributions extend to the IEEE community\, where he has served on the IEEE Fellow and Teaching Award Comm ittees\, chaired the IEEE AP-S and EMC-S Taipei Chapters\, and is currentl y appointed as Track Editor of the IEEE Transactions on Antennas and Propa gation and Associate Editor for IEEE AWPL. He is also a board member of th e Taiwan Microwave Association.\n\nProfessor Chou is a Fellow of IEEE\, IE T\, AAIA\, and AIIA\, and an elected member of the International URSI Comm ission B\, where he also serves as Taiwan member committee's Executive Sec retary.
