New Products — Strategies and Risks for Smaller Firms
Despite the attractions and high profit or growth potential of expansion by new products into new markets, smaller firms, particularly the specialist resource and general sub‐contractors, should think very carefully before committing a high proportion of their resources into developing new products that lead them into new market areas beyond their current experience. The skills of the small marketer—the goal of many new product introductions—can take a long time to acquire.
The Uk Government Small Business Model-a Review
A model, in a very general sense, can best be defined as any device which attempts to provide a simplified representation of reality. The symbolic models used by economists have three major functions pedagogic, explanatory and predictive. Economic models used by government are only concerned with the explanatory and predictive functions. Consequently, any model of the small business sector being used to underpin policy-making in this area, should be judged by its ability to provide clear and systematic insights into current behaviour and by its usefulness as a predictive tool. This approach presupposes two questions. The first question is &dquo;can we deduce an official model of the small business sector?&dquo; The second
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.
