本文提出了一种吸顶式、单蜂窝和多蜂窝RFID系统中天线选择和部署的优化模型。该模型利用三维（3D）天线辐射模式，同时考虑到天线半功率波束宽度和下倾角。具体而言，我们分析了在单小区操作和信号干扰比（SIR）在多小区的情况下，检测概率的小区结构的影响。研究了四种单元结构，即三角形单元、常规矩形单元、偏置矩形单元和六边形单元。还提出了几个设计示例，以显示如何使用该模型来找到最佳配置，以覆盖最大面积的最小数量的天线为一个单一的小区的情况下，以及必须作出的权衡，以实现合理的SIR在多小区操作。我们相信这种优化模型为单电池和多电池RFID系统的优化部署提供了新的见解。
This paper presents an optimization model for antenna selection and deployment in ceiling mounted, single and multi-cell RFID systems. The proposed model utilises a three-dimensional (3D) antenna radiation pattern, taking into consideration of both antenna half power beam width and downtilt angle. Specifically, we have analysed the effects of cell structures on detection probability in single-cell operation and signal-to-interference ratio (SIR) in multi-cell scenario. Four cell structures have been studied, namely, triangular cells, conventional rectangular cells, offset rectangular cells and hexagonal cells. Several design examples are also presented to show how to use this model to find the optimal configuration to cover the maximum area with a minimum number of antennas for a single cell scenario, as well as the trade-offs that have to be made to achieve a reasonable SIR in multi-cell operation. We believe this optimization model provides new insights into the optimal deployment of single and multi-cell RFID systems.
