All About Antennas with Katerina Galitskaya

The Amp Hour · 1 Oct 2024 · Episode 678

What this episode covers

Katerina Galitskaya, a Senior Antenna Engineer, explains the physics of antenna design, emphasizing that ground plane size is critical for efficiency and that lower frequencies require larger PCB areas. She outlines practical rules for PCB placement, such as positioning antennas on the shorter edge and maintaining clearance, while discussing the challenges of human body interaction, SAR regulations, and testing in anechoic chambers. The conversation also covers the limitations of off-the-shelf modules, the complexity of beamforming and millimeter-wave 5G, and the use of simulation tools like EMS to visualize electromagnetic fields.

    398: Clocks Get Into Everything

    Tom Anderson, an engineer at Keysight Technologies who also consults for Alembic, explains the fundamentals of radio frequency (RF) electronics, clarifying that RF issues arise from voltage differentials on wires due to signal propagation delays. He demystifies RF jargon like dBm and Smith charts (which he calls 'dollhouses') and discusses practical design strategies, such as managing clock rise times, avoiding ground plane slots, and tuning antennas using varactors. The conversation also covers the specific electronic challenges of high-end bass guitars, including EMI shielding and signal-to-noise ratios.

    The Spark Gap - Episode 21

    Hosts Carl and Corey discuss PCB layout tips for hobbyists, focusing on component placement and power plane design. They cover decisions like single-sided vs. double-sided assembly, grouping components by functional blocks, and the critical importance of placing decoupling capacitors near IC pins. The conversation also addresses thermal management, power plane sizing, via current capacity, and the use of positive vs. negative layers in CAD tools.

    PCB Grounding Mistakes Your Datasheet Taught You

    Dan Beeker, president of System Solution Specialists and former Technical Director at NXP, explains why PCB grounding mistakes originate in datasheets and reference designs rather than the designer. He argues that the industry wastes hundreds of millions annually by blindly copying evaluation board shortcuts, such as split grounds and unnecessary ferrites, instead of applying field-based physics to manage energy in the dielectric. Beeker highlights critical missing data in datasheets, such as switching speeds and core geometry, and advocates for a shift from traditional circuit theory to 3D electromagnetic field analysis to achieve first-time compliance.

    EMC Expert Debunks Common PCB Grounding Myths

    Todd Hubing, president of LearnEMC, explains that grounding myths stem from confusing signal integrity return paths with EMC ground structures, arguing that high-frequency currents follow the path of least impedance and do not cause ground loops on chassis connections. He debunks the rule that decoupling capacitor placement matters on boards with closely spaced power and ground planes, noting that plane capacitance dominates at high frequencies. Hubing also advises against using common mode chokes on unbalanced power inputs, recommending instead that designers focus on minimizing common mode voltage sources to prevent radiated emissions.

    Intro EMC: Compliance, Opportunities & Pitfalls with Anton Tishchenko

    Anton Tishchenko, founder of PCBforEMC.com and Dr. EMC YouTube channel, discusses EMC compliance strategies, common PCB design mistakes, and his PhD research on 6G metasurfaces. He highlights that EMC testing has a 50% first-time failure rate, often due to simple errors like missing ground planes or improper antenna placement, and explains why pre-certified modules like the ESP32 do not guarantee final product compliance. Tishchenko also details his development of an AI-based PCB analysis tool designed to catch these errors early, while noting the challenges of data privacy and the high cost of simulation software for startups.
