Abstract

High data rates and fast transmission are indispensable for wireless telecommunications. IEEE 802.11 allocates frequency bands of 57 - 64 GHz for the Wireless Gigabit (WiGig) applications. Antennas with high gain that support high frequency are urgently needed. Reflectarray antenna is considered to fulfill the requirements due to each element of the array scatters the incident waves with a certain phase shift to compensate for the different spatial lengths of the feed to create coherent radiation in the desired direction. Moreover, the beamforming technique is counted to obtain a directional signal transmission. This paper proposes a reflectarray antenna operating at 60 GHz. The reflector antenna unit cell model consists of a square patch and a cross patch with the addition of stubs. A complete reflectarray consists of 7 × 7-unit cells in a square of 35 mm array form. The simulation results show a gain of 15.88 dBi with a beamforming of 60°.

用于WiGig波束成形的反射式垂直短节天线设计

高数据速率和快速传输是无线通信必不可少的条件。IEEE 802.11为无线千兆(WiGig)应用分配了57 - 64 GHz的频段。迫切需要支持高频的高增益天线。反射天线被认为是满足要求的，因为阵列的每个元件都以一定的相移散射入射波，以补偿馈电的不同空间长度，从而在期望的方向上产生相干辐射。此外，对波束形成技术进行计数以获得定向信号传输。本文提出了一种工作频率为60ghz的反射天线。反射器天线单元模型由一个方形贴片和一个带有存根的交叉贴片组成。一个完整的反射阵由7 × 7个单元组成，以35毫米的方阵形式排列。仿真结果表明，增益为15.88 dBi，波束形成为60°。
