Specification Part No. : FXP280.07.0100A Model : 868MHz ISM Band Flex Circuit Antenna Features : 75*45*0.1mm 100mm Ø1.13 Cable RoHS SPE-13-8-060/A/PK Page 1 of 10 1. OVERVIEW The Taoglas FXP280 868 MHz ISM Antenna covers from 863-870 MHz used in the 868MHz ISM (Industrial Scientific Medical) European Band. The antenna has been designed in a flexible material with a square form-factor and cable connection for an easy installation. The antenna works on different plastic materials and thickness. We have selected a piece of ABS with 2 mm of thickness as a baseline for testing. 2.
