Description
Overview
With a compact design and robust construction, this circular RFID antenna is resistant to typical environmental influences; the antenna is perfectly suited for applications in agriculture and industrial automation. It is also specially designed to be used in double sided arrangements with a single reader for applications that require large reading volumes. The antenna has a very wide beam width to maximize zone coverage.
