Python Antenna Simulation Module (nec2++) C-style interface
Project description
PyPI module for nec2++
This module allows you to do antenna simulations in Python using the nec2++ antenna simulation package. This is a wrapper using SWIG of the C interface, so the syntax is quite simple. Have a look at the file test.py, for an example of how this library can be used.

Install
As of version 1.6.1.2 swig is no longer required for installation. Simply use PIP as follows:
pip install necpp
Using
# # Simple vertical monopole antenna simulation using python-necpp # pip install necpp # import necpp
- def handle_nec(result):
- if (result != 0):
print necpp.nec_error_message()
def impedance(frequency, z0, height):
nec = necpp.nec_create() handle_nec(necpp.nec_wire(nec, 1, 17, 0, 0, z0, 0, 0, z0+height, 0.1, 1, 1)) handle_nec(necpp.nec_geometry_complete(nec, 1, 0)) handle_nec(necpp.nec_gn_card(nec, 1, 0, 0, 0, 0, 0, 0, 0)) handle_nec(necpp.nec_fr_card(nec, 0, 1, frequency, 0)) handle_nec(necpp.nec_ex_card(nec, 0, 0, 1, 0, 1.0, 0, 0, 0, 0, 0)) handle_nec(necpp.nec_rp_card(nec, 0, 90, 1, 0,5,0,0, 0, 90, 1, 0, 0, 0)) result_index = 0
- z = complex(necpp.nec_impedance_real(nec,result_index),
necpp.nec_impedance_imag(nec,result_index))
necpp.nec_delete(nec) return z
- if (__name__ == ‘main’):
z = impedance(frequency = 34.5, z0 = 0.5, height = 4.0) print “Impedance t(%6.1f,%+6.1fI) Ohms” % (z.real, z.imag)
