Abstract:

The vehicular cellular phone systems initiated a rapid growth of wireless communication .However, with the growth of these systems cell sizes are made smaller and smaller to increase user capacity. Meanwhile along with this growth in outdoor communication the interest in indoor systems like telephony (cordless phones and wireless PABX-es) and data services (e.g. Wireless LAN's) also started. Today as the size of hand-held devices is growing small there is a need to have so many antenna designs which fulfills this demand for ultra-thin, compact sizes and high-performance devices that have the ability to meet multiple standards. This led to the need of designing different types of antenna as per different requirement from the user. To successfully implement a reliable, robust, and high-performing wireless system it is necessary to thoroughly consider the antenna selection and review the requirements of the system in the very early design stages of the hand-held device. This will avoid numerous iterations and unnecessary system redesigns. The objective of this paper is to compare various antennas on the basis of their parameters and applications so that planning for the antenna selection and determining the best one becomes easy. It ensures that the antenna will function optimally. From the perspective of system planning, the choice of antenna selection and deployment options depends on the current and future demand for system performance and the financial resources available. In any wireless communication system, the antenna plays a major role in the reliability and performance of the system.
