Nearfield Antenna Measurement
After many years of development and independent industrial evaluation, near-field antenna testing has come of age and is not only a reliable alternative to far-field testing, but often the preferred approach.
Measurement of sidelobe levels 50 db below the main beam peak and sub-milliradian pointing accuracies have become common place. Conventional far-field measurement ranges are often not adequate for testing such antennas accurately. Near-field measurement techniques have been developed to increase antenna testing accuracy, increase testing throughput, lower testing cost and to provide antenna diagnostics in addition to antenna pattern and gain measurement.
The most common used near-field techniques involve the use of planar, cylindrical and spherical measurement surfaces and together with our partners EMV is able to offer a solution for all three methods. In addition we have solutions for Far-field testing and specifications such as the CTIA test for mobile communication devices. Full turnkey solutions including anechoic chambers are available.
