Abstract

In this paper, a dual-band graphene coplanar waveguide antenna is designed for smart cities and internet of things applications. A graphene film is chosen as the conductive material for the radiation patches and ground plane with a thickness of 240 μm and an electric conductivity of 3.5 × 10 S/m. The dielectric is glass with a dielectric permittivity of 6 and a thickness of 2 mm. The implementation of the antenna on glass permits the integration of the antenna in smart cities and IoT applications. This antenna is based on two trapezoidal patches that generate the dual-band behavior. The overall dimensions of the antenna are 30 mm × 30 mm × 2 mm. The reflection coefficient, gain, and radiation patterns were measured and compared with the simulations. The antenna covers two frequency bands; the lower band covers the 2.45 GHz ISM band, and the upper band range covers from 4 to 7 GHz.

摘要

本文设计了一种用于智慧城市和物联网应用的双频石墨烯共面波导天线。选择石墨烯薄膜作为辐射贴片和接地平面的导电材料，其厚度为240μm，电导率为3.5×10 S/m。电介质为玻璃，相对介电常数为6，厚度为2mm。该天线在玻璃上的实现允许将其集成到智慧城市和物联网应用中。该天线基于两个梯形贴片，产生双频特性。天线的整体尺寸为30mm×30mm×2mm。测量了反射系数、增益和辐射方向图，并与仿真结果进行了比较。该天线覆盖两个频段；较低频段覆盖2.45GHz的ISM频段，较高频段范围为4至7GHz。
