➊
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
➋
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
➌
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.
