摘要

提出了一种适用于无线局域网的新型四波段共面波导馈电叠加天线。该天线采用两个正交的槽形天线,印在相似的无地线基板上,彼此堆叠在一起。已知每个天线都适合双频工作,因此堆叠配置可以使天线在四个不同的频段中都能令人满意地工作。天线工作频带的规格,即中心频率及其相应的频带宽度已经选定,使得天线可以支持大多数高速无线局域网系统,特别是具有WiMAX协议的无线局域网系统。采用Ansof公司的HFSS软件进行天线设计。然后使用CST微波工作室验证结果并优化所需频段的结构。

A New Quad-Band CPW-Fed Stacked Antenna for Wireless LAN Applications
A novel quad-band coplanar waveguide (CPW)-fed stacked antenna suitable for wireless LAN applications is presented. The antenna uses two orthogonal-shaped slot antennas printed on similar groundless substrates stacked at the top of each other. Each antenna is known to be suitable for dual-band operation, so the stacked configuration gives rise to the satisfactory operation of the antenna in four distinct frequency bands. The specifications of the antenna's operating frequency bands, i.e. the center frequencies and their respected band widths have been selected such that most high speed wireless LAN systems especially those with WiMAX protocol can be supported by the antenna. Ansof's HFSS software was employed for designing the antenna. The CST Microwave Studio was then used for verifying the results and optimizing the structure for the desired frequency bands.
