An antenna
has three fundamental properties: gain,
direction, and polarization.
Gain is term used for
measuring of increase in signal power,
described in decibels (dB). Antenna with
a higher gain is more effective in it's
radiation pattern. Every antenna is
designed to raise the power in the
wanted direction and reduce it in
unwanted directions. Gain of an antenna
is reciprocal, meaning it is the same
for transmitting and receiving.
Direction
is the shape of the wireless
signal after leaving the antenna.
Polarization is the
orientation of wireless signal relative
to the earth. It can be vertical,
horizontal, circular or combinations of
these. In WiFi networks most signals are
vertically polarized. Objects that
reflects signal (metallic, water and
glass objects) can affect polarization.
Two antennas with similar polarization
will inter-operate most effectively.

An Grid
type antenna is highly directional antenna
type transmit/receives signals in a very
narrow angle, so they are ideal for long
distance and point to point network
connections.
It has a
main reflector surface that is shaped like a
paraboloid or sphere with an active element
at its focus. That way reflector surface can
reflect parallel signals to a single focal
point.
Parabolic
& dish antennas are the best choice because
very narrow beamwidth will provide you: |
| |
| ●
minimum
interference with another wireless networks
|
| ●
longest signal
distance & faster link |
| ●
improved
security (especially if they are mounted
high) |

An
Omni antenna that sends or receives signals
equally in all directions (360 degrees).
Because of that property, this antenna type
usually have the lowest gain and is used in
point to multipoint links.
An omni directional antenna with an increased
gain will increase distance, but decrease
it's effectiveness above and below the
antenna, while low-gain type will do the
opposite.
Fiberglass construction provides great
protection to the antenna from outdoor
weather conditions. |

Panel
antenna is ideal when aesthetics are
critical because of a flat plastic or
fiberglass cover which gives the antenna a
panel-like appearance.
This is directional antenna (but not to the
degree that a Yagi antenna is used for
both: point to point & point to multipoint WLAN links.
This antennas are usually expensive,
especially sector-panel antenna type.
Because of that, they are unusually used
only by ISP's for hotspots. |
