SMART MOBILE TERMINAL ANTENNAS (SMTAs) FOR WIRELESS COMPUTING NETWORK

The smart antenna for mobile wireless communications systems has received enormous interest world-wide in recent years. However, the application of smart antenna for mobile wireless communication terminal devices and computing network has received little attention. In fact, the smart antenna technology for mobile wireless communications and computing terminals has not been well developed yet due to the complexity of small antenna technology. The Centre of Wireless Monitoring and Application (CWMA) at Griffith University has successfully developed various SMTAs recently. Further research on physical size reduction and optimal design have been carrying out by CWMA’s antenna team, and several new results have been published and the prototype antennas show the potential application in future wireless communications and computing network [1-3]. This paper introduces three basic configurations of Electronically Switched SMTAs (wire SMTA, Dielectric Embedded SMTA and patch SMTA) in Fig. 1 (a) and their design topologies based on numerical techniques of computational electromagnetics. Fig. 1 (b) and (c) illustrate six switched directional beam patterns and 3D beam pattern in far filed. Both experimental and simulation results of these SMTAs have shown a good agreement. (a) (b) (c
