There are hundreds of simple FM transmitter projects on the internet. Most circuits are very similar to each other.
They must be made compactly on a printed circuit board or stripboard, not on a breadboard that has too much stray capacitance between the rows of contacts and many wires.

The radio frequency of simple circuits changes when something moves toward or away from the antenna and as the battery voltage runs down. Most simple circuits are mono, not stereo and sound awful (muffled) since they do not have pre-emphasis (treble boost) used by all FM radio stations.
