Abstract

A low-profile frequency reconfigurable monopole antenna operating in the microwave frequency band is presented in this paper. The proposed structure is printed on Flame Retardant-4 (FR-4) substrate having relative permittivity of 4.3 and tangent loss of 0.025. Four pin diode switches are inserted between radiating patches for switching the various operating modes of an antenna. The proposed antenna operates in five modes, covering nine different bands by operating at single bands of 5 and 3.5 GHz in Mode 1 and Mode 2, dual bands (i.e., 2.6 and 6.5 GHz, 2.1 and 5.6 GHz) in Mode 3 and 4 and triple bands in Mode 5 (i.e., 1.8, 4.8, and 6.4 GHz). The Voltage Standing Waves Ratio (VSWR) of the presented antenna is less than 1.5 for all the operating bands. The efficiency of the designed antenna is 84 % and gain ranges from 1.2 to 3.6 dBi, respectively, at corresponding resonant frequencies. The achieve bandwidths at respective frequencies ranges from 10.5 to 28%. The proposed structure is modeled in Computer Simulation Technology microwave studio (CST MWS) and the simulated results are experimentally validated. Due to its reasonably small size and support for multiple wireless standards, the proposed antenna can be used in modern handheld fifth generation (5G) devices as well as Internet of Things (IoT) enabled systems in smart cities.

摘要

本文提出了一种工作在微波频段的低剖面频率可重构单极天线。所提出的结构印刷在相对介电常数为4.3、切线损耗为0.025的阻燃-4（FR-4）基板上。在辐射贴片之间插入四个pin二极管开关，用于切换天线的各种工作模式。所提出的天线工作在五种模式下，通过在模式1和模式2中分别在5GHz和3.5GHz的单频段工作，覆盖九个不同频段；在模式3和模式4中工作在双频段（即2.6GHz和6.5GHz、2.1GHz和5.6GHz）；在模式5中工作在三频段（即1.8GHz、4.8GHz和6.4GHz）。所呈现天线在所有工作频段的电压驻波比（VSWR）均小于1.5。在相应的谐振频率下，所设计天线的效率为84%，增益范围分别为1.2至3.6dBi。在各个频率下实现的带宽范围为10.5%至28%。所提出的结构在计算机仿真技术微波工作室（CST MWS）中进行建模，并对仿真结果进行了实验验证。由于其尺寸合理小巧且支持多种无线标准，所提出的天线可用于现代手持第五代（5G）设备以及智能城市中的物联网（IoT）系统。
