FM Transmitter Design: uH Value, Coil Parameters, Frequency, Power, and Antenna Choice

Hello!

I have attached some image. In the first figure (pic1), you just see a simple FM transmitter. On the basis of this, I have some doubt.
A transmitter must contain a coil , transistor, variable capasistor,and an antina.
These itoms also depends on circuit volt.
1) What is the relation between frequency , wave’sgeographical spread area and uH?
(Frequency,wave) relation with “uH”
2) What is noise. How it depends on the circuit. How to suppress this?(look pic 2)
3) Relation between uH and coil’s(turn,radious,type(linear,circle..) diameter of coper wire)
uH coil relation and varience with power(in volt)
4) What is the relation between coil and transistor?
5) We use trim capasistor to tune. How its capacitance depends upon the coil,frequency and power?
6) If I need to build 1GHz frequency transmitter. Then what will be the value of uH,transistor,trim capasistor and power(in volt)? Also what type of antina is used?
7) (Frequency, power)-antina relation?
8) I saw some FM transmitter are connected with earth. What is the uses of earthing?

Yes, Colin is right. You're basically asking us to give you a course in radio electronics in one reply. Time for you to hit the library -- or get Googling!

If you have questions along the way -- i.e. something that is unclear in the books or online articles, then bring them here, but to expect us to teach you the whole thing is rather presumptuous. You gotta pay yer dues, there's no other way.

HI. Yo do indeed ask too much as discussed by others, but the circuit shows a little transmitter, which will transmit both FM and AM at the same time. This circuit is going to transmit somewhere in the VHF region. This is indicated by the small No of turns on the coil 7 turns, and the value of the tuning capacitor C4. I would suggest around 40 to 60 MHz.
If you needed to build a 1 GHZ transmitter , the coil will become a piece of transmission line, and the C4 will become likely part thereof.
May I suggest to study a copy of the ARRL Handbook? Any year will do as the basics never change. I believe you will find this publication very enlightening. Incidentally, It would be good to check your spelling, as it looks like you may be lazy if you do not. The subject matter is Radio Transmission. Cheers

thank you. can you answer me the whole questions ,one by one?. this is my request. i like to know more. that is why asking you. hope you will help me........

I hope I can do that for you. I think that you could build this little transmitter. I started out my career by doing just that sort of thing, and I must say it is enjoyable. However I strongly recommend that you also study at least hobby magazines and internet pages along with my answers because radio is a very big subject and I after 40 yrs am still learning.
