Slot Antenna design references.

Hello everyone,
Can anybody suggest a good book or some good papers where slot antenna design is explained. Especially the different configurations like moving feed postion for matching purposes etc..
Any help is appreciated.
Thanks,
Ananth.

This is a very old antenna type. Try some older antenna books. Kraus is one example. In general making the slot nearly a full wavelength long gives you 50 ohms in the center (if my memory is working properly).

Chapter 13 in 'Antennas' by the recently departed J.D. Kraus has a concise section on slot antennas.

I prefer to J.D.Kraus
