Design & Analysis
SuperNEC has a number of predefined
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,
To aid in the design and analysis
process, SuperNEC has a number of predefined
structures such as a parabolic
An example of a yagi array
analysis can be seen here.
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).
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.
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.
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.
Placement Practicle Examples
approach for a placement study is illustrated below:
Generate SIG cross sections
Measure scale model
Compare simulated to measured results
ASEP Flight Profiles
SuperNEC includes a GA Optimiser.
This tool helps antenna designers
to reduce development time and optimise performance.
