Simulation Software:

Some useful simulation software are listed below. Students are encouraged to be familiar with them. Simulations will help the students clarify the theories related to the lab experiments.

GRASP: Reflector antenna simulation software:

GRASP Student Edition (GRASP-SE) is a Student Edition of TICRA's professional General Reflector Antenna Software Package (GRASP). It is a freeware product available for systems running Windows and Linux. The Student Edition allows the user to analyse single or double reflector antenna systems with a single or two feeds. The software can be downloaded from the following website.

http://www.ticra.com/free-downloads/grasp9-se/

FEKO Lite: EM simulation software:

Students are encouraged to download FEKO Lite. It is a free version of FEKO, which is an EM simulation software. Students need to send a request to FEKO for a download link. The instructions can be found on the following link. As it may take a while to process a download request, students are advised to send the request as soon as they can.

http://www.feko.info/download/feko-lite

SABOR: Aperture antenna simulation software:

SABOR is a simple fast tool for analysis of horn antennas and reflector antennas. Most standard geometrical horn antenna and reflector antenna can be simulated using SABOR by inputting the dimension parameters. The software is free to download from the following website.

http://www.gr.ssr.upm.es/sabor.htm

Smith Chart software:

QuickSmith is a Smith Chart based linear circuit simulation program. The software can be downloaded from the following link:

http://www.circuitsage.com/matching/quicksmith.zip

The above software has a simple interface and can perform most of the basic operations including frequency and component sweeps. All students are encouraged to learn the software.

Another Smith Chart related software can be downloaded from the following website:

http://fritz.dellsperger.net/ (main page)

http://fritz.dellsperger.net/downloads.htm (download page)

This software allows more complex operations. This software is only recommended for those students who have specific interest in Microwave networks.

4NEC2: Wire Antenna simulation software:

Students are encouraged to learn 4NEC2 antenna simulation software. The software will help students to visualize 3D radiation

patterns. These simulations will be verified by later experiments performed in the lab. The software is free and can be downloaded from the following website:

http://home.ict.nl/~arivoors/

Students can learn the software from the tutorials found in the same website. Additional tutorials can be found from:

http://www.ece.utah.edu/~ericlundquist/ece3300/4NEC2%20Tutorial%20Germany.pdf

http://coe.uncc.edu/~radams41/ecgr_4121/nec_tutorial.pdf

Students should concentrate on electric dipole antennas, monopole antennas, Yagi - Uda antennas, effect of reflectors near antennas etc.
