In this paper, non-uniform meandered line shunt capacitive RF-MEMS switch is presented at an elliptical patch etched with a split-ring resonator (SRR) for satellite communication applications. The non-uniform meander line shunt capacitive is a fixed-fixed type of RF-MEMS switch that is introduced in this model antenna. The proposed antenna design is resonated at 10.46 GHz with the return loss of −37.6 dB. The performance evolution of the proposed antenna design is evaluated with and without integrated RF-MEMS switch on the proposed antenna SRR. It is observed that the proposed model at the ON-state switch resonates at 10.57 GHz frequency with the return loss of −30 dB. Similarly, at the OFF-state switch, it resonates at 10.53 GHz frequency with the return loss of −43 dB. Al3N4 (aluminum nitride) is used for the switch as a dielectric material, hence the switch attains higher isolation. The actuation voltage of 7.9 V is required for the switch to actuate from ON to OFF state. The switch attains minimum insertion and return loss which is discussed in further sections. The proposed antenna is fabricated and tested by a vector network analyzer; there is a good agreement between the simulated and measured results.

用于卫星应用的具有并联电容 RF-MEMS 开关的椭圆形可重构贴片天线设计

在本文中，非均匀曲折线分流电容式 RF-MEMS 开关呈现在椭圆贴片上，该贴片蚀刻有用于卫星通信应用的开环谐振器 (SRR)。非均匀曲折线分流电容是一种固定固定类型的 RF-MEMS 开关，在此模型天线中引入。建议的天线设计在 10.46 GHz 谐振，回波损耗为 -37.6 dB。在建议的天线 SRR 上有和没有集成 RF-MEMS 开关的情况下，对建议的天线设计的性能演变进行了评估。可以观察到，在导通状态开关处提出的模型在 10.57 GHz 频率下谐振，回波损耗为 -30 dB。同样，在关断状态开关处，它在 10.53 GHz 频率下谐振，回波损耗为 -43 dB。铝3ñ4（氮化铝）用作开关作为介电材料，因此开关获得更高的隔离度。开关从 ON 状态切换到 OFF 状态需要 7.9 V 的驱动电压。该开关实现了最小的插入和回波损耗，这将在后面的部分中讨论。所提出的天线由矢量网络分析仪制造和测试；模拟结果与实测结果吻合良好。
