Mitsubishi Electric: Supports 4 frequency bands for satellite positioning:
-Developing the world’s smallest antenna-
Mitsubishi Electric:
We have developed the “world’s smallest” antenna that supports four frequency bands for satellite positioning.
This antenna:
Of the signal used in satellite positioning
L1 band (1560MHz to 1591MHz),
L2 band (1213MHz ~ 1244MHz),
L5 band (1164MHz to 1189MHz),
L6 band (1257MHz-1299MHz),
Corresponds to 4 frequency bands.
Case size
Horizontal plane is 59 x 59 mm,
With a height of 33mm, it is the smallest in the world.
Antenna miniaturization:
Bent linear antenna elements are wired on the top surface of the housing and the four side surfaces to make it three-dimensional.
For signal reception, it is advantageous to widen the horizontal plane of the antenna.
With this three-dimensional technology, good reception is possible even on a small horizontal surface.
Triple the L1 band compatible band:
Optimized antenna shape in a limited occupied space.
Compared to the company’s conventional products, the bandwidth supported by the L1 band has been expanded by about three times.
Positioning with GLONASS satellites and INMARSAT satellites is also available.
Expand frequency band:
It has become possible to support the world’s major satellite positioning systems and positioning reinforcement services.
Small satellite positioning antenna:
In addition, many high-precision satellite positioning antennas have a diameter of 100 mm or more.
On the other hand, because the antenna is small,
Small agricultural tractors and
It can also be mounted on mobile objects such as drones.
The range of applications will be further expanded.

Mitsubishi Electric Develops World’s Smallest Antenna Prototype for High-precision Satellite-based Positioning in Four Frequency Bands
TOKYO, January 17, 2022
Mitsubishi Electric Corporation
announced today that it has developed a prototype of the world’s smallest* antenna for high-precision satellite-based positioning in four frequency bands used by the world’s main satellite-positioning systems
and positioning-augmentation services.** The highly compact antenna,
which is expected to be installed in diverse vehicles and even drones,
will accelerate high-precision satellite-based positioning for autonomous driving and many other applications.
