Adam Engelbrecht
What I Work On
Antenna & RF Design
- Custom antenna designs from 400 MHz to 8 GHz in high-volume production
- RF front-end chains with triplexer/diplexer integration for multi-radio coexistence
- Design-for-integration strategies in space-constrained, near-metal environments
Testing & Validation
- CST simulation, VNA characterization, anechoic chamber pattern measurements
- S-parameter and isolation analysis for regulatory compliance
- Power meter measurements and spectrum analyzer debugging
AI & Automation
- AI tool integration for measurement parsing and test automation
- Python tooling for antenna data visualization (RFlect)
- Engineering workflow optimization with LLM-assisted productivity
Wireless Protocols
- WiFi (2.4/5/7 GHz), BLE, UWB, 900 MHz ISM
- LTE, LoRa, GNSS
- Wireless power: Qi, AirFuel, NFC
Featured Projects
Open-source tools and projects for RF engineering, antenna analysis, and wireless systems
copper-mountain-vna-mcp
The first VNA MCP server
MCP server that drives Copper Mountain VNAs (RVNA/TRVNA/S2VNA/S4VNA) over TCP/IP SCPI — 45 tools for sweep setup, calibration, S-parameter capture, marker math, and Touchstone export, from Claude or any MCP client.
mcp-remote-access
SSH and Serial port MCP server
MCP server that gives an AI assistant hands-on access to embedded targets — 24 tools for SSH (paramiko) and serial/UART (pyserial), including VID/PID port matching, background commands, prompt-aware reads, and DTR/RTS reset control.
RFlect
Antenna visualization software + 41-tool MCP server
RFlect is an open-source Python tool for visualizing antenna radiation patterns and analyzing RF performance — TRP, efficiency, S-parameters, axial ratio. A desktop GUI plus a zero-dependency MCP server (41 tools) that lets AI assistants drive the full analysis-and-reporting pipeline.
mcp-emc-regulations
EMC/RF regulatory lookup server
MCP server that answers EMC/RF compliance questions from cited standards — 45 tools across FCC Part 15/18/95, CISPR, IEC 61000-4-x, ISO 11452/7637/16750, 3GPP, and ISED, with live eCFR lookups and one-call test-plan generation.
gnss-toolkit
GPS/GNSS testing with publication-quality plots
Python suite for GNSS receiver testing — logs raw NMEA from Telit modules, then computes TTFF, CEP50/95, and RMS error and renders publication-ready accuracy plots. CLI + Tkinter GUI.
VPN-AP
Secure travel router with VPN
Raspberry Pi travel router that broadcasts its own Wi-Fi and routes every client through NordVPN (NordLynx/WireGuard) with a kill switch, captive-portal handling, watchdog auto-recovery, and flexible backhaul (Wi-Fi, iPhone USB tether, or HaLow).
