RFID Antenna Grid System
A custom RFID antenna array with embedded controllers, purpose-built mounting hardware, and software integration.
The challenge
Covering a physical area reliably with RFID meant more than a single reader could provide. Individual antennas produced dead zones, and off-the-shelf hardware offered no clean way to arrange, mount, and coordinate multiple antennas as one system.
The solution
We designed a grid of antennas driven by embedded controllers, with custom PCBs for signal routing and 3D-printed mounting hardware to hold consistent spacing and alignment. A software layer aggregates reads from the array and publishes events over MQTT so the rest of the system sees the grid as a single, coherent source of data.
Outcome
The result is a modular antenna array that can be laid out to fit a given space, with embedded firmware handling coordination and a clean integration point for higher-level software. The mounting hardware makes installation and adjustment repeatable rather than improvised.
Lessons learned
Mechanical layout and antenna placement mattered as much as the electronics. Building the mounting system in CAD early—rather than treating it as an afterthought—saved significant rework once the electronics were in hand.
