标题： Optimization of Dielectric Rod Antenna Design in Millimeter Wave Band for Wireless Communications

摘要： 介质杆天线是用于毫米波频段无线通信的有前途的候选天线。 本工作中提出了在毫米波频段对贴片馈电的介质杆天线设计进行优化。 该设计由简单的介质杆天线组成，采用低成本的聚四氟乙烯材料，相对介电常数为2.1，由矩形贴片天线馈电。 与通常使用的锥形介质杆天线相比，这种配置能够在给定的天线长度下产生更高的增益。 该设计经过优化，在60 GHz时可实现高达17.5 dBi的增益和高达4.4 GHz的阻抗带宽。 提出一个4元阵列以将增益提高到21 dBi。 使用CST微波工作室进行仿真，并展示了仿真结果。 显示英文摘要

摘要： Dielectric rod antennas are promising candidates to be used in millimeter wave band wireless communications. The optimization of a patch-fed dielectric rod antenna design at millimeter wave band is presented in this work. This design is composed of simple dielectric rod antenna made of low cost Teflon with relative permittivity of 2.1 that is fed by a rectangular patch antenna. Compared to the conventionally used tapered dielectric rod antennas, this configuration is capable of producing higher gain for a given antenna length. The design is optimized to achieve gain up to 17.5 dBi and impedance bandwidth up to 4.4 GHz at 60 GHz. A 4-element array is proposed to increase the gain up to 21 dBi. Simulations are performed using CST microwave studio, and their results are presented.
