Pulse Introduces First Mobile Phone Antenna for Full Enclosure within All-Metal Cases

Business Wire
Pulse, a Technitrol (NYSE: TNL) Company, a worldwide leader in
electronic component and subassembly design and manufacturing,
announces the first capacitive-feed antenna that can be enclosed in
an all-metal mobile handset case. Pulse�s capacitive-feed antenna
can be used in mobile phones that operate at 900, 1800, 1900, and
2100 megahertz as well as several antenna manufacturing
technologies such as flexible printed wiring board, laser direct
structuring (LDS), and molded interconnect device (MID).
The antenna radiator of Pulse�s capacitive-feed antenna is
placed at the outside surface of the phone chassis and fed by a
capacitively coupled feed circuit. All available antenna function
is utilized with no loss of signal performance. The antenna
quality, reliability, and operation are based on proven technology
found in all Pulse antenna systems.
The Pulse antenna offers flexibility in phone design and
manufacturing. It can be used either as a stand-alone solution or
integrated, for example, with the all-metal cover. Without having
to coat the antenna with plastic, the metal shell and the antenna
can be constructed as a single unit. The metallic appearance can be
applied to the antenna area or the metal cover. The metal cover can
also be decorated with paint, leather, or other materials without
affecting antenna performance. Integrating an antenna into an
all-metal cover design can result in reduced costs. Pulse optimizes
the knowledge it has gained from working with a broad range of
customer designs and options. A new antenna model can be customized
without having to redesign every model, offering additional
customer savings.
Metal covers are becoming more popular in mobile phones because
they give mobile handsets rigidity and strength, enable thinner
devices with bigger displays, are made of recyclable material, and
provide an effective dispersion of radio engine heat. They are also
popular because the cover is more attractive.
�Although the trend for mobile phones is to encase them
completely with metal, there has not been an antenna that performs
adequately in an all-metal cover. In the past, plastic had to be
used to cover the antenna portion of the handset to enable proper
antenna performance. With Pulse�s new capacitive-feed antenna,
exterior metal parts can now also be used as antennas,� said
Petteri Annamaa, director of research and development for the Pulse
Mobile Division.
The Pulse capacitive-feed antenna is also available as an
antenna/speaker module. Because the antennas are customized for
each manufacturer, the price, lead-time, and delivery depend upon
each customer�s requirements.
Pulse Mobile Division is�a global leader in antennas for mobile
phones. Pulse has combined new ideas with its extensive research
and development capabilities to strengthen its position as a
technology leader in this field. With a unique and far-reaching
understanding of antenna and RF issues regarding modern, mobile
terminals, Pulse Mobile Division has�delivered over 1 billion
mobile antennas.
