Defects_TD2SCDMA_Standards
- 从智能天线的工作原理出发说明使用智能天线时很难实现小区的分扇区应用、多频点天线公 用,因此可以证明智能天线还不是一项可供商用的实用技术 考虑相邻小区/扇区时隙的不对称分 配所产生的相邻小区/扇区收发干扰时,可以证明上、下行时隙实质上是不能按需分配的。3 G使 用的频段是2 GHz,具有传播衰落大、穿透能力差、不易做大范围覆盖。TD2SCDMA标准很难提供3 G标准所规定的在车载、步行、静止环境下分别达到144 kbit/ s、384 kbit/ s和2 048 kbit/ s的无

dual-bandPIFAantenna
- 本论文内容主要包括：设计了一种双频PIFA天线，该天线工作在2.4GHz和5.2GHz。通过加载F形槽和短路探针使天线工作在5.2GHz，通过加载阶梯形槽使天线工作在2.4GHz。具体先理论分析了倒F天线，进行了参数估算。而后使用Designer软件对天线进行仿真，分析了一些参数对该天线性能的影响。最后，得出了该天线最优的一组参数。在此参数下，天线的阻抗带宽在低频段达到130MHz(5.01～5.38GHz)，在高频段达到天370MHz(5.01～5.38GHz)。-This paper sho
