面向三频WiFi应用的分集玻璃天线

Diversity Glass Antennas for Tri-Band WiFi Applications

本文研究了两种新型极化和模式分集玻璃介质谐振器天线(DRAs),用于三频段(2.4 GHz、5.2 GHz和5.8 GHz)无线保真(WiFi)应用。研究比较了这两种DRAs以及一种新型空间分集玻璃DRA,以确定哪种分集天线最适合WiFi路由器应用。同时,将这三种分集玻璃DRAs与一个商业空间分集单极对进行比较,以评估玻璃DRA在WiFi路由器应用中的性能。在极化分集天线中,采用双端口馈电方案来激发不同的DRA模式,并通过使用阶梯形DRA来调节DRA模式的频率。对于模式分集设计,引入堆叠式DRA来扩展圆锥和正侧向辐射模的带宽。所有三种新型分集天线均得到了实验验证。在实验中,还测量了三种玻璃分集天线和参考空间分集单极子天线的误码率(BER),并对结果进行了比较和讨论。实验结果表明,在三种天线中,极化分集全向DRA具有最稳定的BER。

This paper investigates two novel polarization-and pattern-diversity glass dielectric resonator antennas(DRAs),both of which are for tri-band(2.4,5.2,and 5.8 GHz)wireless fidelity(WiFi)applications.It also investigates what type of diversity antenna is most suitable for WiFi router applications by comparing the two DRAs,along with a new space-diversity glass DRA.These three diversity glass DRAs are also compared with a commercial space-diversity monopole pair to benchmark the performance of the glass DRA in WiFi router applications.In our polarization-diversity antenna,a double-port feeding scheme is developed to excite different DRA modes.The frequencies of the DRA modes are tuned by using a stepped DRA.For the pattern-diversity design,a stacked DRA is introduced to broaden the bandwidth for both the conical and broadside radiation modes.All three of the new diversity antennas were fabricated and measured to verify the simulations.In our experiment,the bit error rate(BER)of the three diversity glass antennas and the reference space-diversity monopole antenna was also measured,and the results are compared and discussed.It is found that the polarization-diversity omnidirectional DRA has the most stable BER among the three.
