术语以太网指的是,由通常称为CSMA/CD协议的IEEE802.3标准,所包含的LAN(局域网)产品族。当前,以太网定义了三种速率,操作在光纤和双绞线上。
万兆位以太网正在开发中。
The term Ethernet refers to the family of local-area network (LAN) products covered by the IEEE 802.3 standard that defines what is commonly known as the CSMA/CD protocol. Three data rates are currently defined for operation over optical fiber and twisted-pair cables.
10-Gigabit Ethernet is under development.

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 should include: design of a dual-band PIFA antenna, the antenna works at 2.4GHz and 5.2GHz. F-shaped groove and through the load short-circuit the probe so that the antenna works in 5.2GHz, ladder-shaped slot by loading the antenna work in the 2.4GHz. Detailed analysis of the first inverted F antenna theory, the parameter estimates. Then use the Designer software to simulate the antenna is analyzed some parameters of the antenna performance. Finally, the best of the antenna obtained a set of parameters. In this parameter, the antenna' s impedance bandwidth at low frequencies to 130MHz (5.01 ~ 5.38GHz), to days in the high frequency 370MHz (5.01 ~ 5.38GHz). (2010-12-03, WORD, 156KB, 下载41次)
