How to measure the technology of WIFI antenna
Oct 19, 2017

We have to completely describe a WIFI antenna, there must be a number of radiation and circuit parameters. Respectively, from the lobe diagram, gain, phase, polarization, impedance, power and current dispersion and other measurement techniques.

One: directional lobes

Directional power or amplitude of the lobe diagram of the measurement, usually rotating on the turntable to be tested WIFI antenna and check the acceptance of power changes with the point of view. The field to be measured by the WIFI antenna can be decomposed into two orthogonal components, and the total power is also divided into two lobes, ie, a polarized lobe pattern and a cross-polarized lobe pattern.

The polarization of the antenna should be matched with the corresponding polarization field in the same polarization or cross-polarized lobe diagram.
