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.

Electric Sleeve Dipoles

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)
