Re: Patentable?
You can find a silicon antenna on a Raspberry Pi 3. It is the pale grey rectangle on the corner opposite the Ethernet connector with "Made in the UK" written underneath. The basic principle is a row of field effect transistors. Make the first N transistors conductive and leave the rest high resistance. This gives you an antenna with a variable length suitable for a wide range of frequencies.
