摘要

本文设计了一种紧凑型双频可重构椭圆形贴片天线。所提出的贴片天线具有矩形条状线和带半月形槽的椭圆形,可运行双频。为了实现可重新配置性,在贴片天线的矩形带线上提出了 RF-MEMS 开关。电容并联型射频开关设计了可在 5G 应用中运行的椭圆形天线。在气隙为 3~\mu $ m、致动电压为 5.02 V 的条件下,观察到所提出的 RF-MEMS 开关的位移,以及所提出的横梁可承受的应力高达 85.7 MPa。可重构椭圆形贴片天线的谐振频率分别为 8.34 GHz 和 10.47 GHz,反射系数分别为 -32.28 dB 和 -22.7 dB。在贴片上放置的 RF-MEMS 开关在四种状态下观察到了双频的工作频率和增益。状态 I 的两个工作频率和增益分别为 8.4G Hz 和 10.52G Hz,增益分别为 2.28 dBi 和 2.18 dBi。同样,状态 II 的频率为 8.56 GHz 和 10.55 GHz,增益分别为 2.08 dBi 和 1.30 dBi;状态 III 的频率为 8.49 GHz 和 10.47 GHz,增益分别为 2.48 dBi 和 3.04 dBi;状态 IV 的频率为 8.49 GHz 和 10.49 GHz,增益分别为 2.58 dBi 和 2.64 dBi。本文对紧凑型椭圆贴片天线进行了仿真,并给出了测量值,这两个值是一致的。

RF-MEMS Switch for Reconfigurable With Half-Moon Slots on Elliptical-Shaped Patch Antenna for 5G Applications
A compact dual-band reconfigurable elliptical-shaped patch antenna designed in this article. The proposed patch antenna with rectangular strip lines and an elliptical with half-moon slots presented to operate dual bands. To achieve the reconfigurability, RF-MEMS switches proposed on rectangular strip lines of the patch antenna. The capacitive shunt type RF-switch designed the proposed elliptical antenna to operate at 5G applications. The displacement of the proposed RF-MEMS switch with an air gap of $3~\mu $ m, the actuation of 5.02 V, and the stress of the proposed beam is bearable up to 85.7 MPa is observed. The reconfigurable elliptical-shaped patch antenna resonates at 8.34 GHz and 10.47 GHz with a reflection coefficient of −32.28 dB and −22.7 dB respectively. The operating frequencies and gains are observed at the RF-MEMS switch placed on a patch for dual bands for four states. At the state-I, two operating frequencies and gain are 8.4G Hz, and 10.52G Hz with 2.28 dBi, and 2.18 dBi. Similarly, state-II frequencies are 8.56 GHz, and 10.55 GHz with gains of 2.08 dBi, and 1.30 dBi; state-III frequencies are 8.49 GHz, 10.47 GHz with gains of 2.48 dBi, and 3.04 dBi; and state-IV, frequencies are 8.49 GHz, 10.49 GHz with gain of 2.58 dBi, and 2.64 dBi. The compact elliptical patch antenna was simulated and a measured value is presented in this article and also both values are agreed.
