Abstract: The present invention relates to a RFID reader comprising an antenna system for emitting and receiving RFID signals. The antenna system comprises at least a first inverted F antenna (10) and a second inverted F antenna (11) each comprising a feed element (101,111), a radiating element (102,112) having a first end coupled to the feed element and a second end free, and a tuning element (103,113) having a first end coupled to the ground plane and a second end coupled to the first end of the radiating element. The radiating elements (102, 112) of the two inverted F antenna extend in a first direction and a second direction respectively, said first and second directions being offset by a non-zero sequential rotation. In addition, the two inverted F antennas are isolated from each other by a quarter wavelength slot (160) etched in the ground plane between the two antennas.
