2023年3月29日 · dBi（isotropic-全向）的参考基准为自由空间的全方向性天线，它最能表达实际环境的比值单位，许多天线厂家也常用dBi来标天线的增益值。 一般认为dBi和dBd表示同一个增 …

dBi和dBd都是标识功率增益的相对值，但dBi的参考基准为全方向性天线(isotropic antenna)，而dBd的参考基准为偶极子天线(dipole antenna)，一般认为，表示同一个增益时，用dBi表示出 …

NOTE: Some companies present the gain of their antennas in dBi, not dBd, as most do. That makes it look like they have the same (or more) gain as other antennas, but subtract 2.15 dB …

2020年2月10日 · How is dBi Measured? Antennas may have a rating measured in dBi. This is the amount of power an antenna can send or receive from a specific direction. To the end of the …

For the commonly utilized half-wave dipole, the particular formulation works out to the following, including its decibel equivalency, expressed as dBi (decibels referenced to isotropic radiator):

Use this calculator to find the max output power of a transmitter in Watt from the antenna gain in dBi. For this calculation, Effective Isotropic Radiated Power (EIRP) is also required.

Data Bus Inversion（DBI）：数据总线翻转. 数据总线翻转功能的优势： 只支持X8跟X16的颗粒，X4颗粒不支持； 配置是按照每字节设置的（X8颗粒上有一个 DBI_n 脚，X16颗粒上有 …

2020年9月19日 · 本文解释了无线路由器中dBi的含义及其重要性，并探讨了不同dBi数值对信号传输距离与覆盖范围的影响。 在无线 路由器 参数中，常常可以看到天线增益一项，数值单位 …

This simple tutorial illustrates the concepts of antenna gain, the dB, and the dBi terms. You can understand it all with no math !

常用衡量天线增益的单位是dBi和dBd。 对于dBi，其基准为理想的点源天线，即一个真正意义上的“点”来作天线增益的对比基准。 理想点源天线的辐射是全向的，其方向图是个理想的球，同一 …
