Abstract

The paper introduces an efficient procedure that allows the design of low cost magnetic antennas with arbitrary shape and extremely reduced dimensions. The technique does not need any optimization procedure and it can be applied to any antenna geometry, even very complex ones, e.g., with fractal shape. Simulations have been compared to measurements, proving a good agreement and an excellent performance in terms of radiation efficiency, not only in free space, but also when the antenna is collocated inside dissipative media. For this reason, the device can be efficiently proposed for the realization of the terminal unit in wireless sensor networks, especially when the node must be embedded inside lossy material.

具有复杂几何形状的磁前端用于水和液体中的无线传感器网络
本文介绍了一种设计任意形状和极小尺寸的低成本磁性天线的有效方法。该技术不需要任何优化程序,可以应用于任何几何形状的天线,甚至是非常复杂的天线,例如分形天线。仿真结果与实测结果进行了比较,结果表明,不仅在自由空间,而且当天线配置在耗散介质中时,在辐射效率方面都具有良好的一致性和优异的性能。因此,该装置可以有效地用于无线传感器网络中终端单元的实现,特别是当节点必须嵌入有损耗材料中时。
