We will find out how they basically work, what commercial one I got is the best and how to make your own. Along the way we will also answer the question whether a bigger antenna is better? There will be tons more like Impedance matching, VNA measurement and resonance circuits! Let's get started!! ;-) Websites shown in this video: https://www.lcdwiki.com/res/PublicFile/esp32-s3_hardware_design_guidelines_en.pdf https://en.wikipedia.org/wiki/Dipole_antenna https://en.wikipedia.org/wiki/Radiation_pattern Thanks to Mouser Electronics for sponsoring this video 0:00 Bigger Antenna = Better? 1:01 Intro 1:34 The Job of Antennas 2:31 Resonance?? 3:46 Antenna Length? 4:30 WiFi Antenna Experiment 6:40 Dipole Antenna 6:55 Monopole Antenna 7:41 Making a DIY Antenna 8:27 Antenna Resonance 9:17 50ohm Impedance 9:34 VNA Tool? 10:06 Verdict
