Abstract: A method and apparatus are provided for controlling access to given premises for a user. The method includes a prior step of creating an access ticket giving access to a travel service, the ticket being a reproduced transport ticket enabling this user to make a journey, a graphical identifier being integrated in the access ticket and associated with information making it possible to make the journey when the access ticket reproduced on a medium is read. The method further includes reading the ticket at at least one given premises independently of the journey, and subsequently unlocking an electric door opener triggered by the reading of the graphical identifier reproduced on the medium for allowing access to at least one of the given premises.

Abstract: A wideband antenna system is capable of radiating or receiving radio-frequency signals in a given frequency band, comprising at least two substantially collinear radiating elements, wherein each element radiates in one frequency band, a first radiating element working in the [Fhinf, Fhsup] frequency band, a second radiating element working in the [Fminf, Fmsup] frequency band. At the hinge frequencies, these two elements participate in the radiation.
