This hands-on preparation session will int roduce fundamental antenna concepts and practical measurement techniques u sing a Vector Network Analyzer (VNA).\n\nParticipants will review key ante nna parameters such as impedance\, VSWR\, bandwidth\, and frequency respon se\, with a focus on understanding how these concepts apply to the antenna systems that will be used during the Fox Hunt Challenge. For antenna desi gn and preparation purposes\, the target operating band for the challenge will be the 915 MHz band.\n\nParticipants who already have an antenna prot otype designed for the 915 MHz band are welcome to bring it so it can be m easured and discussed during the session. Please note that this workshop i s focused on antenna concepts and VNA measurements\, and it is not intende d as a full antenna construction workshop. This activity is free of charge and intended for confirmed participants of the IEEE AP-S Fox Hunt Challen ge 2026.\n\nParticipants are encouraged to bring their laptop\, charger\, a notebook or device for taking notes\, and\, optionally\, an antenna prot otype or SMA connector/adapters if available.\n\nAgenda: \n4:00 p.m. – 4 :10 p.m. Welcome and introduction to the IEEE AP-S Fox Hunt Challenge 2026 \n\n4:10 p.m. – 4:35 p.m. Basic antenna concepts for radio direction fin ding Impedance\, resonance\, polarization\, radiation patterns\, and bandw idth\n\n4:35 p.m. – 5:00 p.m. Introduction to VNA measurements S-paramet ers\, return loss\, VSWR\, and antenna matching\n\n5:00 p.m. – 5:40 p.m. Practical demonstration: measuring antennas for the 915 MHz band\n\n5:40 p.m. – 5:55 p.m. Discussion of participant antenna prototypes\, if avail able\n\n5:55 p.m. – 6:00 p.m. Final recommendations and next steps for t he challenge\n\nBldg: Edificio 411 - Laboratorio de Ingeniería\, Av Kra 3 0 #45 03\, Universidad Nacional de Colombia\, Bogotá D.C.\, Distrito Capi tal de Bogota\, Colombia\, 111321 LOCATION:Bldg: Edificio 411 - Laboratorio de Ingeniería\, Av Kra 30 #45 03 \, Universidad Nacional de Colombia\, Bogotá D.C.\, Distrito Capital de B ogota\, Colombia\, 111321 ORGANIZER:apscolombia@ieee.org.co SEQUENCE:16 SUMMARY:Basic Antenna Concepts and VNA Measurements – IEEE AP-S Fox Hunt Challenge 2026 URL;VALUE=URI:https://events.vtools.ieee.org/m/566763 X-ALT-DESC:Description: <br /><p>As part of the preparation activities for the IEEE AP-S Fox Hunt Challenge 2026\, the IEEE Antennas and Propagation Society Colombia Chapter invites registered participants to attend the wor kshop "Basic Antenna Concepts and VNA Measurements".
