#678 – All About Antennas with Katerina Galitskaya

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
