Paper Abstract

For the past few decades, the world observes a tremendous growth in the fundamental concepts based on higher dimensional quantum structures. Several reports and results have been reported in the leading journals consistently on optical sources like light emitting diodes and laser diodes, modulators/switches and detectors by deploying the concepts of periodical structures like quantum wells, quantum dots and porous silica. Certainly in the world of ultra high-speed communication, the above said devices will pave way to get the best performance out of it. In general, antenna is the most inevitable part of wireless communication systems, particularly, desirable bandwidth with demanded directivity, compactness, high efficient antennas are expected to materialize in the future generation (4G) cellular mobile communication, mobile computing and personal communication services. In this paper an attempt has been made to study the radiation characteristics of quantum structures (QW, QWR, and QD). These radiation characteristics are compared with that of the conventional current carrying element. It is found that the radiation properties are much better than the conventional current carrying elements. Hence, radiators based on these structures can be made with high efficiency, directivity and low power consumption. Thus, this work paves a way to develop novel radiators to meet the demands of the future communication systems.
