Well Suited
Application
SuperNEC has a number of predefined
antenna assemblies
making it easy and quick to design and analyse antennas. Users
can also add to this library of antenna types and structures.
SuperNEC is well suited to
design and analyse wire structure antennas such as yagi's,
log periodic dipole arrays, helix
antennas, loops, dipoles,
monopoles etc.
To aid in the design and analysis
process, SuperNEC has a number of predefined
structures such as a parabolic
dish, plates,
cylinders, boxes,
cones etc.
An example of a yagi array
analysis can be seen here.
 Capable
of Simulation
SuperNEC is capable of simulating
structures and antennas like a horn or waveguide. It is however
not an optimal tool for this analysis as it requires large
amounts of memory and time.
Other structures that SuperNEC
can simulate are patch antennas (without dielectric substrates).
Not capable
of Simulating
SuperNEC is unable to accurately
simulate electrically small antennas (typically smaller than
one tenth of a wavelength).
SuperNEC is not capable of
simulating complex microstrip structures.
Future
Development
Development which will allow
SuperNEC to simulate multiple dielectric layers with the antenna
on it or embedded, is underway.
This will enable patch antennas
with dielectric substrates to be simulated.

Placement Studies
|
|
SuperNEC can be used to determine
the optimum placement of antennas on structures.
Typical structures include
aircraft (such as the Boeing 707, Puma helicopter, Hawk aircraft
and C-130), ships and masts.

SuperNEC includes a GA Optimiser.
This tool helps antenna designers
to reduce development time and optimise performance.
