TECHNICAL PERFORMANCE

Low loss and high effi ciency

Azimuth pattern symmetry is within ± 0.1 dB

variation as specifi ed by the CTIA for ripple
testing according to the OTA Test Plan

DESIGN

Innovative low loss structure with a protective

external

radome

Excellent rotation symmetrical structure

minimizing cross polarization level

The radiating structure is orthogonal to the feeding

line, minimizing cable and feed point interaction

The radiating structure is entirely metallic without

the use of external discrete components

Innovative choke design further reduces cable

interaction by attenuating the natural return
currents from the magnetic dipole

REPEATABILITY

Stiff and robust mechanical design

Precision machined

High reliability connector

REFERENCE ANTENNAS

The magnetic dipole or magnetic
loop antenna is complementary
to the electrical dipole, with a
similar radiation pattern but in
orthogonal polarization.
