LOG PERIODIC DIPOLES
20 MHz - 18 GHz
TRANSMIT - RECEIVE
Constant beamwidth over wide band of operation and typical
radiation pattern of log periodic antennas make these
antennas ideally suited for generating uniform fields over a
large area.
Several high gain arrays and broadband antennas which
can handle power levels in excess of several kilowatts are
available for immunity testing per IEC 1000-4-3, MIL-STD
and SAE requirements. All log periodic antennas from
ARA
TECH offer a cross polarization rejection in excess of 20dB,
especially suited for measurements per CISPR 16-1.
Four types of log periodic antennas for EMC emission and
immunity testing are offered. These are
LPD and LPV
series linearly polarized antennas, LPC series dual
polarized antennas, and
LPA series high gain arrays.
LINEARLY POLARIZED
LPD series antennas are linearly polarized, log periodics
designed to transmit and receive signals over a broad
frequency range. These antennas are characterized by a
high front-to-back ratio, excellent SWR and medium power
gain at all frequencies in the band. Polarization adjustment
is possible in any plane, with a universal joint.
High quality aluminum construction with all stainless steel
hardware make for a lightweight, high strength antenna that
will provide years of trouble-free operation. For emission
testing or low power transmit applications, an assortment of
low profile
LPDs are available. These antennas are
constructed on cost-effective copper clad dielectric
materials.
LPDs exhibit the same performance standards as
our other antennas, but with cost savings to the customer.
Standard LPD antennas are intended for relatively
permanent installations.
LPD series antennas operating
below 400 MHz are also supplied in a kit form for storage
and transportation. Antennas in the kit form assemble
easily with minimum tool requirements.
The Vee configuration, LPV series log periodic antennas give greater power gain than that obtainable
with a planar log-periodic antenna of the same length and taper. The short length of the
LPV-2010/C
antenna restricts the movement of the active region as a function of frequency to a relatively small
volume, which is desirable in RFI measurements.
