dear all,
i'm new to antenna design. currently i got to design a single antenna which covers bluetooth, 3G and Wi-Fi bands. i plan to print/design the antenna on the PCB.

i come a across a antenna book explaining pros and cons of each antenna. the book is "design of ultra wideband antenna matching network". however no much point given on which antenna is the best for my requirement.

my requirements are:

1) low SAR
2) high efficiency
3) low S11
4) smaller size (as small as possible)

can anyone tell me which antenna is suitable for my application and the reason why? PIFA or FICA or some other antenna?

Hi
I would build both and check their performance, or at least model them.

Interesting and bewildering at the same time. Not absolutely sure what you're describing but if Chip, who is into fractal antennas, is any where around I'm sure he can give you some really useful information.
Have fun

Dave's rules of small antennas:

Small
Efficient
Wideband

Pick any two

hi WX7G,
i would pick small and wideband.

hi W9GB,
thanks alot for so many useful articles. after reading those, i feel im not new to antenna anymore. :D

thanks alot for the inputs guys. i really appreciate it.

dear all,
Is there any material available on FICA design. detail guide on how to design FICA?
