An RFID transponder including an antenna, a chip having at least one transmission and reception circuit as well as a memory, a dielectric carrier element which is covered on a first surface with a structured first metallization and which is covered on a second surface disposed opposite the first surface with a second metallization. The first and second metallizations are mutually electrically conductively connected, thereby forming the antenna. The first metallization is structured such that it forms two electric terminals of the antenna arranged on the first surface of the dielectric carrier element. The chip can be or is electrically contacted via these two terminals. An adaptation network is at least partly formed by the structuring of the first metallization and adapting the input impedance of the antenna in a conjugate complex manner to the impedance of the chip.

RFID transponder, in particular for assembly on metal and manufacturing method therefor

A system and a method for monitoring grouped objects with a gateway and a plurality of radio nodes attachable to the objects. Each radio node has a computing unit, a short-range communications unit and an energy supply unit. One of the radio nodes or the gateway has a localization unit. Optionally, one of the radio nodes also has a long-range communications unit. The computing unit contains a control program for the processing of predetermined tasks in radio nodes, which is designed for the control of bi-directional communications between the radio nodes via the short-range communications unit for the formation of an ad hoc network. The control program undertakes the control of a tuning process between the radio nodes and selects one of the radio nodes for the processing of one of the predetermined tasks, the selected node at that instant being best suited for the task according to predetermined criteria.

System and method for the monitoring of grouped objects

A method for monitoring a group of objects, and an arrangement to implement the method includes providing each object of the group to be monitored with a radio node of a self-networking radio network, whereby each radio node within the group has a unique identification. The radio nodes of the group automatically reveal themselves at a starting time and network with one another. The radio nodes of the group monitor themselves from the starting time and convey at least one specified change in an initial mutual situation. At least one of the radio nodes when notifying or recognizing a specified change, conveys information concerning the change to a monitoring unit and/or controls an alarm transmitter for activating an alarm.
