Antennas
Pulse Electronics introduced three specialized antennas
Package ProxAnt
TL 1.0 combines
Proximity Sensor with
an Antenna to optimize
both Functions
Pulse Electronics Corporation
introduced an all-in-one combination
antenna and proximity
sensor package to optimize the
characteristics of both functions,
thus enabling better device performance
and increased design
flexibility for tablets, laptops,
and notebook computers. The
ProxAnt TL 1.0 is a seven band
main antenna, a proximity sensor
chip, and all needed components
included on the same flexible
circuit board. Without requiring
physical contact, the sensor recognizes
when it is close to the user
and sends a signal to the host
processor to reduce the transmission
power to the antenna, thus
lowering SAR. The sensor also
recognizes movement to avoid
a false trigger.
Dimensions for the antenna carrier
(X x Y x Z) are 60 x 11.2
x 4.2 mm. The proximity sensor
footprint dimension (X x
Y) is 13 x 8.8 mm. The proximity
sensor area extends 6 mm
from the antenna carrier in the
Y-dimension and occupies the
same volume as the antenna to
optimize space utilization in a
compact module. During product
development design changes are
flexible and easier because only
the ProxAnt package needs optimization,
and not the main PCB.
“The ProxAnt optimizes the
antenna and proximity function
as one entity, instead of separately.
This integration minimizes
the combined size and simplifies
logistics to give the best possible
antenna performance,” explained

Unit. Pulse Electronics´ ProxAnt
TL 1.0 supports WiFi WLAN
802.11n, ac standards all LTE
bands, and is SAR compliant.
Antenna
miniaturization
technology enables
high data rates in tight
spaces that require 3x3
MIMO configurations
Pulse Electronics Corporation
introduced a new method of
constructing antennas to enable
high data rates in tight spaces
that require 3x3 multiple input
multiple output (MIMO) configurations
such as tablets, laptops,
and notebook computers.
Pulse‘s new DenseAnt TL 1.0
advanced manufacturing antenna
technology fits three WLAN
antennas in physically the same
volume as was used for two LDS
antennas without compromising
performance or isolation. The
antenna is composed of high
dielectric materials to realize a
4-dB-improvement in isolation
over standard plastic substrates,
achieving higher performance
even when integrated in close
proximity with each other. The
antennas are customized for each
application and configuration,
optimizing them for size and
performance.
„High-speed data rate applications
require MIMO technology,
which increases the number of
antennas required in a device,“
explained Jon Yu, GM for Pulse
Electronics Wireless Consumer
Business Unit. „At the same
time, the space allocated for
the antennas is limited. Pulse‘s
DenseAnt miniaturization concept
utilizes advanced manufacturing
technology combined
with the use of advanced materials.
This technology enables
multiple antennas to be closely
integrated with each other thus
enabling high throughput while
achieving optimal space utilization
in a cost effective way.“
Pulse Electronics‘ DenseAnt
TL 1.0 supports WiFi WLAN
802.11n, ac standards. These
customized antennas are proven
and ready to be implemented in
any project.
“Plume Series”
Dual-Band flexible
internal antenna is
smaller and more
efficient for IoT
applications
Pulse Electronics Corporation
started a new internal dual-band
flexible printed circuit (FPC)
antenna to provide connectivity
and data transmission for
Internet of Things applications
DenseAnt TL 1.0 optimizes isolation and performance of small
computers
