Combined multifunctional RFID communication device
First Claim
1. Device for communicating with RFID-tags, the device comprising:
- an antenna unit configured and arranged for an appliance and comprising a first antenna and a second antenna spatially displaced from each other and connected in series by a twisted pair of wires, anda controller circuit connected to the antenna unit and configured for communication with the appliance,wherein the controller circuit is adapted to sequentially feed different polling signals to the antenna unit, with time between the sequentially fed different polling signals for detecting possible responses from the respective ones of the RFID-tags, by feeding a current that runs through each of the first antenna and second antenna such that the first antenna and the second antenna simultaneously radiate each of the sequentially fed different polling signals, and by detecting one of the possible responses the controller circuit further communicates data via at least one of the RFID-tags on behalf of the appliance.

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).
