As far as the experts I spoke with know, there are no modules or instruments that would enable the fix you require (notifying users if an antenna goes offline). However, an external module may not be necessary. I spoke with Impinj, which says all its readers support a feature that generates an event if an antenna becomes disconnected. Impinj’s software development kits provide examples of how to enable this feature. Additionally, the company’s IoT device interface automatically generates antenna disconnect and connect events. You can learn about the interface here. SensThys also reports that its readers have a built-in red/green system that displays a red light if an antenna isn’t operating.
