NEC Corporation today announced the successful development
of a
wideband wearable antenna.
The wideband wearable antenna is an antenna that uses a
conductive
fabric which can be attached to clothing and other items, or folded up
for easy carrying. It is a high-performance mobile antenna that can
act as a supplementary antenna in areas with poor reception.
Antennas are generally designed to operate in an open space,
and if
used in close proximity to a human body or other object, the impedance
deteriorates, causing a noticeable reduction in performance. This
antenna is designed to demonstrate equally good impedance
characteristics whether used in an open space or close to a human body,
for example when attached to the user's clothing.
One of the difficulties encountered in the past when using
conductive
fabrics was that soldering was not possible. In the case of this new
antenna, power is supplied to a small flexible print substrate by a
soldered coaxial cable, so that power supply is possible through
capacity coupling with the substrate.
NEC will first test reception of digital terrestrial broadcasts in the
470-770 MHz band. Later, it will test the potential of this antenna
as an external antenna for terminals in the future, conducting ongoing
development while studying potential future applications.
