Advanced monopole antenna with a wide beamwidth for the assessment of outdoor 5G wireless communication environments

摘要

Abstract >We propose an advanced monopole antenna to investigate non‐stationary outdoor wireless channel environments of 5G mobile communications. Our antenna has an omni‐directional beam pattern in the azimuth plane and a wide half‐power beamwidth (HPBW) in the elevation plane, respectively. To minimize blind angles along the axis of the monopole, we intentionally add a metallic annular ring around the monopole, which operates as a secondary source of our antenna. Then, the circumferential field from the secondary source appropriately interferes with the primary field from the monopole to widen the HPBW with a relatively high antenna gain in a far‐field region. An input signal is applied to a standard WR‐28 waveguide, and it is transferred to the monopole antenna through a coaxial waveguide. However, because impedance looking into the monopole and the waveguides are all different, we insert a mode converter between the rectangular and the coaxial waveguides. For better impedance matching, the coaxial waveguide is also used as an impedance transformer between the mode converter and the monopole antenna. Consequently, we can obtain the required omni‐directional radiation pattern with a wide HPBW and a high gain. All measurement data show good agreement with simulations, which proves the validity of our approach. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span>

>我们提出了一款先进的单极天线，以调查5G移动通信的非静止室外无线频道环境。我们的天线在方位角平面中具有全向光梁图案，分别在仰角平面中的宽半功率束宽度（HPBW）。为了沿着单极的轴线最小化盲角，我们有意地在单极上添加金属环形环，其作为我们天线的次级来源操作。然后，来自二次源的圆周场适当地干扰来自单极的主场，以在远场区域中具有相对高的天线增益的HPBW。输入信号被施加到标准WR-28波导，并且通过同轴波导将其传送到单极天线。然而，因为看着单极和波导的阻抗都不同，所以我们在矩形和同轴波导之间插入模式转换器。为了更好的阻抗匹配，同轴波导也用作模式转换器和单极天线之间的阻抗变压器。因此，我们可以以宽的HPBW和高增益获得所需的全向辐射模式。所有测量数据显示与模拟的良好一致，这证明了我们的方法的有效性。</
