Abstract
New concepts are required to realize really effective antennas for broadband wireless access systems. Broadband wireless access system antennas cannot be the same as existing wireless system antennas, such as those for fixed terrestrial systems and narrow band mobile communication systems. The difficulties arise because broadband systems need tracking wireless terminals and mitigating multi-path phenomena. Differences in design procedure for broadband wireless antennas are described and it is pointed out that the design objects of antennas must be determined by evaluating all transmission line phenomena. Practical and effective antennas for broadband wireless access systems are described which have been developed in the NTT Wireless System Laboratories. The possibility of developing an adaptive antenna is also investigated as a powerful antenna of the future.
