1. Introduction
This ceramic multiband cellular antenna
uses high grade ceramics which have
been developed in Taoglas through years
of expertise in delivering the right materials
for high performance antennas.
1.1 Key Advantages
Taoglas designers, through constant
research and development have been able
to “fit” 6 bands in a small area, while also
achieving high efficiency. The PA.25 is a
unique SMT solution which is delivered on
tape and reel. For very detailed
integration information additional to
this specification please download
our comprehensive PA.25 integration
application note from our website.

Highest efficiency in small size
35*5*6mm. A comparative metal,
FR4, FPC, whip, rod, helix antenna
would have much more reduced
efficiency in this configuration for
the same size due to their different
dielectric constants.
More resistant to detuning compared
to other antenna integrations.
If tuning is required it can be tuned
for the device environment.
There is no need for new tooling,
thereby saving money if
customisation is required.
Highly reliable and robust– its
predecessor the PA.22 antenna is
used by the world’s leading auto
makers in extremely challenging
environments. The antenna meets
all temperature and mechanical
specs required (vibration,
drop tests etc)

Rectangular shape - Easy to
integrate. Other antenna designs
come in irregular shapes and sizes
making them hard to integrate.
SMD (On-Board) antenna saves on
labor, cable and connector costs,
leads to higher integration yield
rates, and reduces losses
in transmission.
It can be mounted directly on edge
of device main-board.
Transmission losses are kept to
absolute minimum resulting in
much improved over the air (OTA)
device performance compared to
similar efficiency cable and
connector antenna solutions

9.
Reductions in probability of radiated
spurious emissions compared to
other antenna technologies are
observed when using the PA.25 and
strictly following this application
note layout
Achieves moderate to high gain
in both vertical and horizontal
polarization planes.
This feature is very useful in certain
wireless communications where the
antenna orientation is not fixed and
the reflections or multipath signals
may be present from any plane.
In those cases the important
parameter to be considered is the
total field strength, which is the
vector sum of the signal from the
horizontal and vertical polarization
planes at any instant in time.
