Antennas laboratories may also do the following tests:

Return Loss and VSWR Measurements: Assessing the antenna's efficiency in transmitting and receiving signals Testing
Radiation Pattern Testing: Evaluating the directional properties of antennas to understand how they distribute energy in space Testing
Gain Measurements: Determining the ability of the antenna to direct or concentrate radio frequency energy in a particular direction Testing
Polarization Testing: Verifying the orientation of the electromagnetic field produced by the antenna Testing
Impedance Measurement: Checking the antenna's impedance to ensure it matches the connected circuit for maximum power transfer Testing
