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.
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.
1.1 Key Advantages
1. Highest efficiency in small size 36*6*5mm. A comparative metal, FR4, FPC, whip, rod,helix
2. More resistant to detuning compared to other antenna integrations. If tuning is required it can
3. Highly reliable and robust– its predecessor the PA.22 antenna is used by the world’s leading
4. Rectangular shape - Easy to integrate. Other antenna designs come in irregular shapes and
5. SMD (On-Board) antenna saves on labor, cable and connector costs, leads to higher
6. It can be mounted directly on edge of device main-board.
7. Transmission losses are kept to absolute minimum resulting in much improved over the air
8. It exhibits a reduction in backward radiation toward the user’s head compared to other antenna
9. Reductions in probability of radiated spurious emissions compared to other antenna
10. Achieves moderate to high gain in both vertical and horizontal polarization planes. This feature
antenna would have much more reduced efficiency in this configuration for the same size due
to their different dielectric constants.
be tuned for the device environment. There is no need for new tooling, thereby saving money
if customisation is required.

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.
