Abstract: In various embodiments, an antenna arrangement is provided. The antenna arrangement includes a first antenna and a second antenna. The first antenna and the second antenna are arranged substantially in the same plane. The first antenna and the second antenna are arranged with respect to one another in such a manner that an intermediate area is defined between the first antenna and the second antenna. The antenna arrangement further includes a controller which is configured to control the first antenna and the second antenna in such a manner that a magnetic field produced in the intermediate area is greater, in terms of magnitude, than the magnetic field generated by the first antenna in the intermediate area and the magnetic field generated by the second antenna in the intermediate area.

Abstract: A method for controlling the flow of data in a near field communication appliance having an interposed element and a plurality of secure elements connected to the interposed element is disclosed. The method includes receiving a first communication at a first one of the secure elements. The first communication is sent by an external appliance and suited to an application located in one of the secure elements. The method further includes testing, by means of the first secure element, whether the first secure element contains the application. The first secure element is muted if the first secure element does not contain the application. A corresponding near field communication appliance and terminals are also disclosed.
