Abstract

A multiband tri-branch monopole antenna is presented. The antenna structure is constructed of radiating patches with three branches. It is fed by a microstrip transmission line. Essentially, the antenna is a simple structure created by a step impedance technique. In addition, the antenna can be separately regulated for each operational frequency band of 2.44 GHz, 3.36 GHz, and 5.52 GHz by the height of a central patch, a right patch with a thin strip line, and a small patch on the left, respectively. The antenna is manufactured on a size of 50x35 mm2 FR4 substrate with a thickness of 0.8 mm and a permittivity of 4.3. The suggested antenna is appropriate for network board internet of things (NB-IoT) technology working at 2.4 GHz/5.2 GHz/5.8 GHz (WLAN), 3.5 GHz (WiMAX), and 2.3 GHz/2.6 GHz/3.5 GHz (5G technology). The antenna’s radiation pattern is omnidirectional, and its average gain is approximately 2dBi.

基于阶跃阻抗技术的WLAN、WiMAX、5G和IoT多频段三支路单极天线

提出了一种多波段三分支单极天线。天线结构由具有三个分支的辐射片构成。它由微带传输线馈电。从本质上讲，天线是由阶跃阻抗技术创建的简单结构。此外，天线还可以在2.44 GHz、3.36 GHz和5.52 GHz的每个工作频段分别通过中央贴片、右侧带细条形线的贴片和左侧小贴片的高度分别进行调节。该天线采用50x35mm2 FR4衬底，厚度为0.8 mm，介电常数为4.3。建议的天线适用于2.4 GHz/5.2 GHz/5.8 GHz (WLAN)、3.5 GHz (WiMAX)和2.3 GHz/2.6 GHz/3.5 GHz (5G)的网板物联网(NB-IoT)技术。天线的辐射方向图是全向的，其平均增益约为2dBi。
