Lens Antenna Method, Vertical Incidence Type
Electric Wave Absorber, Return Loss Measurement System
JIS R1679 : 2007/IEC 62431 : 2008

Model No. EAS07

EAS07 is a vertical measurement system for evaluations of electric wave absorbers and shield materials.

Unlike coaxial or waveguide type, errors by air gap do not occur because sample is not capsulated in the fixture.

Despite its compact dimensions, your sample can be measured with plane wave, with lenses are attached to the antennas, which provids high measurement accuracy.

Samples can be smaller than conventional systems because they can be placed in the vicinity of the antennas.
