Antenna Gain measurement

How can we measure the antenna gain in-house ? Assume we only have reference dipole, signal generator and spectrum available only measurement.

to choose a given gain antenna as a reference .

You must have a electromagnatic shielding room.
Else, the result of antenna pattern will not be adoptable.

you must have chamber to test efficiency and gain.

天线测试包括:天线端口阻抗(网分),效率,增益等

必须要有屏蔽暗室，一个用来校准的标准天线，3D扫描支架。

一般说来，没有像专门的天线制造商那种的设备，很难测得很准

电磁波箱，频谱仪，好的电缆，bnc
