Hi,
I needed some help to design and construct a proper antenna for the FM transmitter. Can anybody help me with this or provide me with some links. Any help would be greatly appreciated.
Thanks!

Nothing beats "The Antenna Book" from the ARRL.

However, for a basic low power transmitter, usually a few feet of wire will work just fine...

I made a simple FM antenna for my Sirius Satellite radio car kit's FM transmitter, and now the sound quality is excellent.
The length of the antenna is not critical. I have listed the optimum length for 88.5 MHz, but your car's external FM antenna uses one length to cover the whole FM band because there is not a large penalty for being off slightly in the length. Similarly, the antenna wires don't have to be kept perfectly straight. I tucked mine into the seam along the top of my dashboard so that it's mostly out of sight.
