RFID Antenna Cables: How to Get Better Performance in Real Projects
A lot of people focus on rfid readers and tags when building an RFID system. Makes sense—but in real projects, that’s not always where the problem is. More than once, we’ve seen systems underperform just because of the antenna cable. Same reader, same tags—swap the cable, and suddenly the range improves. So yeah, this “small part” matters more than most people expect. Let’s go through what actually makes a difference. 1. Signal Loss Is Real RFID signals don’t just travel through the air—they also go through the cable first. And every meter of cable eats a bit of that signal. If the cable quality is poor, you’re basically losing power before it even reaches the rfid antenna . We’ve seen setups where: Everything on paper should reach 8 meters In reality, it barely hits 5 Switch to a better cable, and the range comes back. Not magic—just less signal loss. 2. Cable Length: Try Not to Push It Sometimes you don’t have a choice—reader here, antenna over there, and yo...
