Adam Engelbrecht

RF Engineer III

6+ years designing antennas and RF front-ends for embedded wireless platforms. Currently focused on multi-radio coexistence, custom antenna integration, and AI-driven engineering workflows.

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

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.

RFlect

software

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.

VPN-AP

networking

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).
