Abstract: There is described a device (100) for communicating with RFID-tags, the device (100) comprising (a) an antenna unit comprising a first antenna (110; 200) and a second antenna (120; 200), and (b) a controller (130) connected to the antenna unit. The controller (130) is adapted to sequentially feed different polling signals to the antenna unit such that corresponding signals are individually and simultaneously radiated by each of the first antenna (110; 200) and second antenna (120; 200). There is also described a home appliance comprising the aforementioned device (100). Furthermore, there is described a method for communicating with RFID-tags by an antenna unit comprising a first antenna (110; 200) and a second antenna (120; 200). The described method comprises sequentially feeding different polling signals to the antenna unit such that corresponding signals are individually radiated by each of the first antenna (110; 200) and second antenna (120; 200).
