A critical part of executing a successful UHF RFID project is ensuring adequate antenna coverage of the read point. Antenna coverage is best considered during the design phase of a project, when there are many options to ensure proper tag reads. Antenna coverage must be checked during the commissioning phase, which may uncover gaps in antenna coverage. If corrective action is required during commissioning, the RFID application engineer has some options to eliminate the deficiencies. The option selected depends on the specific application and the RFID application engineer’s professional judgment.
