Depends on what technology is used. If you are talking about an oscillator built from a semiconductor devices then the frequency of a free running oscillator might be like 200 GHz without any frequency multipliers. With multipliers you can boost the frequency to a few Terahertz.
Then there is what's called a photomixing, where they use a special mixer to mix 2 lasers to produce IF in the Terehertz range.

yes, but what I am trying to say is that is it possible to emmite visible light out of an antenna.

Your eyes have antennas or cones that are of a specific lengths that resonate at red, green and blue frequencies. The wavelength is the size of the cell basically.
You are asking what is the highest attainable frequency by an oscillator? Well, an electromagnetic wave at any frequency can be achieved by different methods.
Gamma rays at the end of the electormagnetic spectrum are generated by a radioactive decay.
The highest ever frequency detected eminated from cosmic rays which was a single proton carrying energy of 50 Joules.

It's true, in general, that waves of any frequency can be manufactured with methods that vary from simple RF electronics up to particle accelerators. It is not true, however, that you can use something like a simple dipole antenna to produce gamma rays.

Size for one thing.chromosome24 said:
The smallest conceivable dipole is probably 2 atoms.
Gamma is quite a bit shorter than the diameter of a single atom.

Related to Highest attainable frequencies by a transmitter
1. What are the highest attainable frequencies that can be transmitted by a transmitter?
The highest attainable frequencies that can be transmitted by a transmitter depend on various factors such as the design and capabilities of the transmitter, the type of signal being transmitted, and the surrounding environment. Generally, the highest frequencies that can be transmitted range from a few gigahertz (GHz) to several terahertz (THz).
2. What factors affect the highest attainable frequencies of a transmitter?
The highest attainable frequencies of a transmitter can be affected by factors such as the transmitter's power output, the quality and stability of its components, and the design and materials used in its construction. The surrounding environment, including atmospheric conditions and interference from other electronic devices, can also impact the highest frequencies that can be transmitted.
3. How can a transmitter achieve higher frequencies?
To achieve higher frequencies, a transmitter must have components that are capable of handling the higher frequencies, such as high-frequency transistors and capacitors. The design and construction of the transmitter must also be optimized for higher frequencies, and it must have a stable and accurate frequency source. Additionally, the surrounding environment must be carefully controlled to minimize interference.
4. Is there a limit to the highest attainable frequencies of a transmitter?
Yes, there is a limit to the highest attainable frequencies of a transmitter. This limit is determined by the physical capabilities of the transmitter's components and the surrounding environment. As technology advances and new materials and designs are developed, this limit may be pushed higher.
5. What are the potential applications for transmitters with high attainable frequencies?
Transmitters with high attainable frequencies have a wide range of potential applications. They can be used for high-speed data communication, radar and imaging systems, medical equipment, and scientific research. They are also crucial for the development of advanced wireless technologies such as 5G networks and satellite communication systems.
