The PATCH-25 antenna covers both the EU and USA RFID bands. The antenna is waterproof and easy to install. It is circularly polarised and can be read in any orientation. Due to its circular polarisation, it can also be used to improve GSM coverage indoors.
The VSWR is typically less than 1.3:1, giving a return loss of more than 20 dB. This antenna is unique in the RFID environment due to its VSWR & gain specifications.
