Abstract

Anultra-wideband (UWB) bowl-shaped monopole antenna with a sturdy, simple, and lightweight structure is proposed, and then is used to compose the 3 × 3 multiple input multiple output (MIMO) antenna. The wide bandwidth is determined by the outline of the monopole, which has a quarter wavelength and high-order modes. The inner part of the bowl-shaped monopole is removed for a light weight. The simulated and measured results show that an ultra-wide band of 2.3–8.1 GHz (5.8 GHz, 111.5%) and a high isolation of greater than 20 dB between the antenna elements of the MIMO antenna can be achieved.

一种结构简单、坚固的超宽带MIMO碗形单极天线

提出了一种结构坚固、结构简单、重量轻的碗形单极天线，并将其用于组成3 × 3多输入多输出(MIMO)天线。宽带宽是由单极子的轮廓决定的，单极子具有四分之一波长和高阶模式。为了重量轻，将碗形单极子的内部去掉。仿真和实测结果表明，MIMO天线的天线单元之间可以实现2.3 ~ 8.1 GHz (5.8 GHz, 111.5%)的超宽带和大于20 dB的高隔离。
