Quo vadis, logistica?
This abstract answers the following questions: "Is it necessary to do things differentia telly?", "Do new strategies express new technologies as well?", Are the cost savings still important?, "Which effects can be achieved by logistic solutions?", Things are necessary to where they can be done better?", "Which are limits of that?", "How does the development effects the logistic market?", "Could firms choose the right logistic partners?".

Ceramic microwave antennas for mobile applications
Due to their medium to high permittivity values, ceramic microwave materials are attractive as building blocks for miniaturised antenna solutions. Further advantages are low dielectric losses and an excellent temperature stability of standard ceramic materials. Yet, the permittivity of the ceramic material also has a strong influence on the radiation efficiency and bandwidth of the antenna. This implies that in the design process a suitable compromise has to be found between the degree of miniaturisation on the one hand and the antenna efficiency and bandwidth on the other. We describe two approaches towards efficient miniaturised ceramic microwave antennas: the dielectric resonator antenna (DRA) with partial metallisation and the shorting post patch antenna. We focus on design steps taken to ensure both a high degree of miniaturisation and high values of the radiation efficiency, the choice of the ceramic material and the experimental performance of the antennas.
