Metal Back Plane Usage:
Emits RF Illumination more strongly towards the front of the antenna
If the coverage zone is required to be just on the front side of the Wave Antenna, one can
add a metal ground plane (such as aluminum foil) to the back side of the antenna.
The back-ground plane can be mounted directly behind the 7’ antenna,
but
for the 3’ and 5’
antennas, the metal plane
must be
mounted using a ¾” spacer such as a ¾” foam piece.
The antenna gain will increase based on the size of the ground plane. If the ground plane is
roughly the same size as the antenna, the gain will increase by about 1.5dB. For example,
the gain of the 3’ antenna is about 3dBi, which will increase to 4.5dBi with a ¾” spacer and a
backplane the same size as the antenna. If the back plane is significantly larger than the
antenna, then the gain may increase by as much as 3dB.
We currently have two options for ground planes. The first is the standard foam and foil
ground plane referred to as the
“Standard”
in the above picture. The standard version is
made using a ¾”
foam
backing covered in aluminum foil. Our other option is referred to as
the “Special Order”
ground plane and is available for an additional charge. The Special-
order option is made out of a ¾”
corrugated plastic
covered in aluminum foil trimmed with
a white vinyl tape on all edges. This option is used in areas that need improved aesthetics
for very public areas such as an office atrium, medical facilities, or company offices.
