Kathrein Xpol antennas for polarization diversity
represent the latest development stage in anten-na technology. An ever increasing number of net-
work operators are coming to appreciate the real
advantages of only having to install 3 dual +/- 45
polarized antennas for a complete 3 sector site,
where previously 6 or 9 vertically polarized anten-
nas had to be installed.
For polarization diversity to function properly it is
very important that the different polarized signals
are as independent as possible of each other
(principle of uncorrelated signals). The most
important point of view in this context is the
so-called Cross-polar ratio (CPR), i.e. the ratio
of the signal levels of similar polarizations com-pared to dissimilar polarizations. The CPR should
be quoted for the whole sector width (+/- 60), not
just for the main radiating direction.
The antenna gain is already considerably redu-
ced at the sector edges, therefore a CPR as high
as possible is desired. The system suppliers
demand at least 10 dB for +/- 60from the main
direction. Kathrein Xpol antennas more than fulfil
these requirements in this critical area.

Most of the Xpol antennas on the market are
based on the so-called patch technology and on
printed circuit boards for power-splitting purpo-
ses. Kathrein, however, have for many years
used the proven dipole-type technology together
with a low-loss cable harness, which clearly
offers more opportunities for perfecting certain
antenna characteristics.
We present the new, so-called A-Panels as our
concept for the 900 MHz Xpol antenna range. We
adapted the excellent and well proven mechani-
cal design used in our range of GSM 1800 anten-
nas for these A-Panels. Instead of a fibre-glass
cover screwed and sealed to an aluminium back-
plate, the radome now consists of a closed, self-
supporting fibre-glass profile into which the metal
parts of the antenna are inserted. There are no
drill-holes at all in the profile which is closed by
two end caps with short sealing rings. This com-
pletely closed design offers ideal permanent pro-
tection against environmental influences and also
increases the mechanical stability of the anten-
nas.
Apart from the existing comprehensive range of
Xpol antennas which can be found in our catalo-
gues, we now also have low gain versions for
GSM 900 with a length of 656 mm.
1. Excellent cross polar ratio over azimuth
The dipole design delivers remarkable cross
polar ratio not only in the main direction but also
across the complete sector.
2. Low intermodulation products
Unlike printed circuit antennas, the intermodulati-
on products are typically -150 dBc
4. High isolation
Patent pending decoupling elements ensure an
isolation between the two polarization inputs of
min. > 30 dB (typically 35 dB)
5. Constant electrical performance under badweather conditions
Due to the dipole design, rain, ice and snow have

The demand for Dual Band Antennas is constant-
ly increasing as ever more GSM 900 operatorsare also getting GSM 1800 licences. A few simple
versions are already available on the market, i.e.
versions for vertical polarization or antennas with
dual-polarization, where the 900 MHz and 1800
MHz systems are arranged separately, one
above the other. At the end of 1998 resp. begin-
ning of 1999 Kathrein will be launching sophisti-
cated Dual Band Antennas which are able to ope-rate in the cross-polarization mode with
interlocked radiating elements for both 900 MHz
and 1800 MHz, whereby the antenna length is
determinated by a single band 900 MHz version.
Moreover, two different versions will be available:

1. Only one antenna is required for both bands.
2. All the advantages of Kathreins single bandXpol antennas also apply to Kathreins Dual Band
Antennas.
3. The dimensions are identical to those of a pure
900 MHz Antenna. If an existing GSM 900 station
is extended to become a GSM 900 / 1800 stationthe appearance, wind load and the type of attach-
ment will all remain unaltered.
4. The solution using integrated combiners leads
to considerable savings in feeder cables; if an
existing site is upgraded no further feeder cablesare required apart from those already installed.
5. The enclosed data sheets nos. 741 320 / 741
322 and 741 326 / 741 327 show antenna versi-
ons of 1.3 m and 2 m length. We are also plan-
ning to introduce further versions with lengths of0.65 m und 2.6 m.
Kathrein Dual Band Antennas therefore offer the following advantages:

Unobtrusive omni antennas for both GSM 900
and GSM 1800 are now available especially for
microcell applications. These versions are similar
to our Indoor Antennas, but are suitable for out-
door operation and are fitted with an N connector.

Whilst the desired downtilt angle remains con-
stant over the whole azimuth range for antennas
with electrical downtilt, this is only achieved in the
main radiating direction for antennas with mecha-
nical downtilt and is reduced to 0 in the +/ 90
Common coverage calculations for network plan-
ning cannot take this effect into account and
under certain circumstances it can be the reason
for unexpected interferences caused by other

Downtilt angle varies over the azimuth range:set downtilt angle only in main direction (0),no downtilt in tilt axis direction (+/-90from main beam).
Horizontal half-power beam width increases withrising downtilt angle.
Resulting gain reduction depends on azimuth direction(can rarely be considered in network planning).
Constant downtilt angle over the whole azimuth range.
Horizontal half-power beam independent ofdowntilt angle.
Identical gain reduction for all azimuth directions.
