Performance
The TDK RF Solutions VLA-8001 V-Log
Periodic Antenna offers a wide frequency range of 80 MHz to 1 GHz with
enhanced gain over standard log periodic dipole array antennas. The VLA-8001
features equalized E and H plane beamwidths, and its unique feed design
(patent pending) provides improved high frequency response and greater power
handling capabilities.
Robust Design
The VLA-8001 is built for the harsh
environments associated with EMC testing. It features an ultra-robust
mechanical design and a highly durable feed to withstand the rigors of daily
use

The stacked
Logarithmic Periodic Dipole Antenna consists of two ordinary Log Periodic
structures.
The excellent characteristics (flat gain over a large bandwidth,
low SWR) of the ordinary Log.-Per. designs could be maintained using the
stacked LP design. The stacked design helps to focus the directional pattern
of the H-plane somewhat, resulting in a typical gain improvement of ca. 2-3
dB compared to an ordinary LPDA. This is especially important for immunity
testing, where a maximum fieldstrength and a good field uniformity is
required. The beamwidth in the E-plane and the H-plane are nearly identical,
providing an optimised illumination of the EuT with minimised ground
reflection influence. Further the STLP 9128 C has an excellent cross-polar
rejection.

The stacked Log Periodic
Dipole Antenna (Stacked LPDA) consists of two ordinary Log.-Per. structures.
The excellent characteristics (flat gain over a large bandwidth, low SWR) of
the ordinary LPDA designs could be maintained using the stacked LPDA design.
The stacked design helps to focus the directional pattern of the H-plane
somewhat, resulting in a typical gain improvement of 2.5 dB compared to an
ordinary LP antenna. This is especially important for immunity testing,
where a maximum fieldstrength and a good field uniformity is required. The
beamwidth in the E-plane and the H-plane are nearly identical, providing an
optimised illumination of the EuT with minimised ground reflection
influence.Further the cross polar rejection of the STLP 9128 D is excellent.
The fastlinks allows to disassemble the rear elements without any need for
further tools within a few seconds. These fastlinks divide the antenna into
five parts, which can be stored and transported easily.

The STLP 9129 was especially designed for wideband immunity tests. The
unique STLP 9129 is able to cover the entire frequency range from 70 MHz to
10 GHz with a typical isotropic farfield gain of 8.6 dBi with a ripple of
less than +/- 2.3 dB only. This unrivalled bandwidth was achieved by
combining the both well proven antenna designs STLP 9128 D and the
STLP 9149.
The STLP 9129 does provide the optimum out of gain and
field uniformity at the same time as well as both basic antennas do.
Main Application: Generation of defined high field strength levels for
radiated immunity testing acc. IEC 61000-4-3.
