This article focuses on the incorporation of smart antennas into multiplatform devices. With the growth of wireless technologies, there is growing interest in multiplatform devices with embedded Wi-Fi, cellular, WiMAX, IEEE 802.20, and other such technologies. Each of these technologies will increasingly use smart antennas. Therefore, providing such antennas for each technology on a multiplatform device causes a serious problem. However, the implementation of a universal smart antenna front-end overcomes this problem. Wireless access services have grown substantially with the expansion of cellular technology and the introduction of new communication systems. Since each system has advantages and disadvantages in different situations, the growth of these systems is expected to continue. There are various advantages of using smart antennas in these systems. These antennas provide increased range, more uniform coverage, higher data rates, multipath mitigation, and interference robustness. If multiplatform devices are to get the full benefit of each system, then smart antennas must be incorporated into each of these systems.
