Abstract
An antenna for providing light is disclosed. The antenna may comprise a substrate having at least two domains and a light source which is connected to two domains. The light source may emit light when a direct current flows from one domain to another domain. A radio frequency (RF) current flows through the domains for generation of radio waves. A capacitor is provided between adjacent domains to provide a path for the RF current to bypass the light source. The substrate is enabled to absorb the heat dissipated by the light source. The substrate is coated with a reflective material to reflect impinging light rays.
Claims6
A dipole antenna for providing light, the dipole antenna comprising:
- two sides, each of the two sides comprising:
- a substrate having at least two domains;
- a light source connected to the domains;
- and
- a capacitor coupled to the at least two domains and configured to provide a path for radio frequency (RF) current to bypass the light source;
- and
- a RF choke electrically coupled to the two sides;
- wherein the light source emits light when a current flows from one domain to another domain.
