Abstract

This paper presents the design of a triband antenna that can be electronically configured to operate at different frequencies. The proposed antenna is design to operate at sub-6GHz bands at 2.45 GHz (ISM, Wi-Fi, and WLAN), 3.3, 3.5 & 3.9 GHz (WiMAX), and 4.1 & 4.9 GHz (4G & 5G). This is achieved by connecting two open-ended stubs to a modified triangular patch radiator using PIN diodes. The antenna's performance was optimized using a 3D electromagnetic solver and its performance was verified through measurements. Moreover, the conformal analysis done on the antenna shows that the proposed technique can be used in moderately flexible wireless devices without compromising the antenna's gain, radiation efficiency and radiation patterns. These characteristics makes the proposed antenna applicable for various wireless communication systems and devices.

摘要

本文提出了一种可通过电子配置在不同频率下工作的三频天线设计。所提出的天线设计用于在低于 6GHz 的频段工作，工作频率分别为 2.45GHz（ISM、Wi-Fi 和 WLAN）、3.3GHz、3.5GHz 和 3.9GHz（WiMAX）以及 4.1GHz 和 4.9GHz（4G 和 5G）。这是通过使用 PIN 二极管将两个开路短截线连接到改进的三角形贴片辐射器来实现的。使用三维电磁场求解器对天线的性能进行了优化，并通过测量对其性能进行了验证。此外，对天线进行的共形分析表明，所提出的技术可用于中等柔性无线设备，而不会影响天线的增益、辐射效率和辐射模式。这些特性使得所提出的天线适用于各种无线通信系统和设备。
