DLC Integrated GHz Antenna for Aerospace

In this work we have fabricated and measured the frequency response of a diamond-like carbon (DLC) antenna based on a monopole layout. DLC has been deposited on a silicon substrate at room temperatures by sputtering a graphite target with Ar gas. The antenna presents a low reflectivity at 5.47 GHz suggesting its use in super high frequency (SHF, from 3 to 30 GHz) wireless communication systems, including aerospace transmissions. A good agreement between measured and numerical S-11 response has been found.
