Reference Antennas

Electric Sleeve Dipoles

380 MHz - 5900 MHz

Electric Sleeve Dipoles are used for gain reference, efficiency reference for low gain antennas and chamber reflectivity evaluation (directivity, cross polarization, radiation pattern). CTIA/3GPP low gain antenna measurement.

TECHNICAL PERFORMANCE

Low loss and high efficiency
Azimuth pattern symmetry is within ± 0.1 dB variation as specified by the CTIA for ripple testing according to the OTA Test Plan

DESIGN

End-fed sleeve dipole technology, minimizing cable and feed point interaction
Innovative choke design further reduces cable interaction by attenuating the natural return currents from the dipole
Azimuth pattern symmetry thanks to entirely symmetrical design

SURFACE TREATMENT

Surtec 650 according to MIL-C 5541E class 3
Polyurethane paint

REPEATABILITY

Stiff and robust mechanical design
Minimal use of dielectric materia
Precision machined
High-reliability connector

DELIVERED DOCUMENTS

Typical performance data (TYMEDA™)
Measured return loss data

EQUIPMENT

High precision coaxial connector
Customizable sleeve dipoles kit for OTA/WiFi testing of mobile devices (Optional)
