#678 – All About Antennas with Katerina Galitskaya

The Amp Hour Electronics Podcast

Welcome Katerina Galitskaya!

• Chris started following Katerina’s antenna posts on LinkedIn
• Monopole vs dipole
• Lower frequences are harder bc longer wavelength
• PCB size half of frequency
• Place antenta on the shorter side
• How to ruin your PCB
• When to go to a antenna engineer?
• Where will the device be?
• Antenna environment
• Start from vacuum, start adding elements
• Dummies in the lab. The one in the episode photo is a dummy head filled with liquid (?!)
• SAR – Specific Absorption rate
• Simulation vs lab work (dimensions)
• Anechoic chamber
• When to go with custom antenna?
• Buying off the shelf antenna?
• New Airpods with fancy 3D antenna
• Ben’s video about laser sintered antennas
• MIMO / Beamforming
• the failed promises of 5G
• When to simulate
• Some open source programs out there (“EMSee”?)
• Simulating vs visualizing
• Most of the time it’s not about vizualizing fields
• What is the iteration elements of the antenna?
• Satellite antenna design
• Good to go external
• Thinking about the dielectric const of case
