arly this year, I twice visited Islamabad, Pakistan. The first visit was for an invited presentation in the 8th International Bhurban Conference on Applied Sciences & Technology (IBCAST 8), held from January 9 to 12, 201 1 , at the National Centre for Physics (NCP). This was organized by Centres of Excellence in Science & Applied Technologies (CESAT), Islamabad. The second visit was for a three-day EMC course Jgave at the Advanced Engineering and Research Organization (AERO). This is a development and production center for airborne military and commercial systems in Pakistan. It works under the umbrella organization of the National Engineering and Scientific Commission (NESCOM).
I met wonderful people from military and commercial R&D groups, and established good friendships during these visits. Although I had given this EMC course to many compa nies and institutions in Turkey and abroad, this was the first course where the emphasize was put on military EMC prob lems. These courses are also education for me, because of the discussions with the attendees who experience a variety of EMC problems. One of the issues we discussed this time was loop antennas, especially those used in low-frequency military conducted susceptibility and emission (CS/CE) tests.
We did prepare a few tutorials on antenna fundamentals and concepts, as well as calibration, not only for well-known communication and EMC antennas, but also for measurement environments [ 1 -3]. I realized that we haven't done that for loop-antenna measurements and calibration. Therefore, the next issues' tutorial will be on loop-antenna calibration.
The Quiz for this Issue
David, our antenna expert [2], is going to design and pro duce a home-made loop antenna and then calibrate it:
How do you design a loop antenna?
What types of loop antennas are used in military CS/ CE tests?
Which standards are used for loop-antenna calibra tion?
How do you compare different standards?
