Compact Antennas for Wireless
Smaller than normal size with larger than normal performance
|
Focused Wave Technology (FWT) Antennas
offer greatly reducing size, while maintaining the gain of full (150 -
300 % larger) sized structures. FWT antennas focus radio energy
increasing communications range or reducing the power required for a
fixed range. Normally, the size of the antenna and focusing elements
force physical dimensions to be 1/2 wavelength in size. With
FWT materials combined with proven antenna geometries, a new
standard for antennas is now possible. FWT reduces each
antenna dimension by a factor of two (or more), reducing volume by a
factor of eight. Several antenna styles can benefit from FWT
advantages, including PIFA, Dipole, Planar Array, and Parabolic
Dishes. |

FWT produces a planar and smooth shape that is perfect for
portable handheld systems as well as tower and wall mounted antennas,
significantly easing mechanical loading. What's more, the conformal
shape complements the aesthetic design qualities of your product.
FWT antennas offer an intrinsic balanced
transmission line that is important to the efficient and wide
bandwidth delivery of electrical energy directly to the antenna's
radiating elements, providing improved termination impedance.
FWT antennas offer a natural structure for integrating active
components within the body of the antenna, and can contain the
antenna, diplexer filter, active switch, RF pre-amp, TX gain stage,
and even complete radio transceiver modules and chip sets.
Standard Features
- FWT offers a reduced size & volume, 8:1, for same gain.
- FWT increases useful range! Gain > 1 dBi for very small size; > 5
dBi for surprisingly small sized, but always a substantial size
shrinkage factor.
- FWT has
built-in matching elements and a differential balanced driver
component.
- FWT can be customized for special shape factors or specific
antenna pointing factors.
- FWT has a natural platform to add active devices your Logo for
OEM use.
- Specifications - FWT Antennas can be built from 49 to 10,000 MHz.
Custom, wide- bandwidths and broadcast power wave shaping apertures
available.
