Italo.gr-Antenna Modelling

In this section, Antenna modeling concepts are presented. Specifically, you can download a paper that involves the modelling of the antennas listed below:

A/A	Antenna
1.	ELECTRICALLY SHORT DIPOLE
2.	HALF WAVELENGTH DIPOLE
3.	QUARTER-WAVE MONOPOLE
4.	SQUARE LOOP ANTENNA
	1. Small Perimeter
	2. Big Perimeter
	3. Square loop alternative
5.	CORNER REFLECTOR
6.	CIRCULAR POLARIZED ANTENNA

The paper can be downloaded here (5.3 Mb) and the Excel document here (8 Kb).Moreover, for the 6 antennas that are modelled in the paper, there exists: a NEC file which was used to simulate the radiation patterns, the wavelengths, the frequency and a MATLAB file which was used to create the current graphs. These files can be found in the table provided:

A/A	Antenna	NEC file	MATLAB file	Doc, Excel
A.	ELECTRICALLY SHORT DIPOLE	1	1	Check above
B.	HALF WAVELENGTH DIPOLE	1, 2	1	Check above
C.	QUARTER-WAVE MONOPOLE	1, 2	1	Check above
D.	SQUARE LOOP ANTENNA
	1. Small Perimeter	1	1	Check above
	2. Big Perimeter	1	1	Check above
	3. Square loop alternative	1	1	1, 2
E.	CORNER REFLECTOR	1	1	Check above
F.	CIRCULAR POLARIZED ANTENNA	1	1	Check above

In order to perform the simulations you must have Antenna modelling software. I can recommend you software to download like:

1.3

NEC_WIN_Plus-Demo	Part 1	Just download both and open
NEC_WIN_Plus-Demo	Part 2	one of them with winrar

11.2

I don't know the versions of Windows that are supported, though i used WindowsMe to make them work. The Nec_WIN_Plus-Demo has an evaluation period of one month. If it expires, try changing the date from the control panel and it will work again.Finally, it is advisable to check the references below.

	This is the official webpage where you can find NEC_WIN Plus and other Antenna software which is not free of charge. There are also some very nice Antenna examples.
The unofficial Numerical Electromagnetic Code (NEC) Archives	There is a lot of software to download in this webpage. The software i used for the simulations, can also be found in this webpage.
