company is always seeking to develop products to
meet buyer and market demands.We continue to improve
our products with advances in design,efficiency
At the same time we are developing new products
and breaking into new markets.
Our measuring and testing
Voltage Standing Wave Ratio (VSWR)
determine matching between the antenna and the transceiver
in the prototype.
Best possible matching, over the entire band, is essential
to minimizing power losses. Based on the result of VSWR
measurements Evertime can also carry out network matching.
To get the best possible impedance match between transceiver,transmission
line and antenna. In this measurement the VSWR result
is optimized by choosing the proper layout and component
values for the matching net, and the maximum potential
of the antenna is shown.
Transmission line optimization
get the best possible impedance match between transceiver,
transmission line and antenna. In this measurement the
VSWR result is optimized by minimizing the attenuation
between the antenna and the transceiver through testing
and design of the transmission line.
3D radiation pattern
show the radiation pattern of the antenna when mounted
in the actual device. This measurement is needed to
assure the required functionality. You can easily see
if an antenna really is sufficiently omnidirectional
or if a directional antenna has the expected radiation.
Specific Absorption Rate (SAR)
verify compliance with national/international regulations
concerning SAR (absorbed electromagnetic energy in humans).
Electrical and magnetic field measurements
examine the electrical and magnetic fields on the surface
of the product (prototype) and antenna. This is one
of the most important measurements and the result is
used during the development process to verify functionality
and to ensure SAR compliance.
also provide consultancy services covering the design,
development, application and implementation of your
particular antenna solution.
