摘要

本文介绍了平衡馈电双频内置天线的基本设计、优化和总体性能。采用基于16并行PC集群系统的高效并行矩量法，对该天线包括附加参数h3在内的4个主要关键结构参数进行了优化，以适应日本双频运行。经过结构参数优化，得到了2.4 GHz频段340 MHz的带宽和5 GHz频段480 MHz的带宽。同时，对金属板上的射频电流进行了评估，以验证所提出的平衡馈电天线的有效性。最后，对优化后的天线构型进行了实验评价。测量结果表明，2.4 GHz频段的带宽为246 MHz, 5 GHz频段的带宽为325 MHz，足以满足日本2.4 GHz无线局域网系统和5 GHz室内无线局域网系统的指定频段。

Three dimensional structural parameter analysis on a balanced-fed dual-band built-in antenna for wideband wireless LAN systems

This paper describes the basic design, the optimization, and the overall performance of the balanced-fed dual-band built-in antenna. The four major key structural parameters of this antenna including the additional parameter h3 were optimized for the dual-band operation in Japan using the efficient parallel Method of Moment based on the 16 parallel PC cluster system. The bandwidth of 340 MHz for 2.4 GHz band and that of 480 MHz for 5 GHz band have been obtained after the structural parameter optimization. Also, the RF current on the metallic plate was evaluated in order to confirm the validity of the proposed antenna with balanced-fed. Finally, the optimized antenna configuration was evaluated experimentally. The measurement results demonstrate the bandwidths of 246 MHz for 2.4 GHz band and 325 MHz for 5 GHz band, which are sufficiently wide for the assigned frequency bands for the 2.4 GHz WLAN system and the 5 GHz indoor W LAN system in Japan.
