Antennas with light source
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.
1 . 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.
2 . The dipole antenna of claim 1 , wherein the current is a direct current.
3 . The dipole antenna of claim 1 , wherein an RF current flows through the domains for generation of radio waves.
4 . The dipole antenna of claim 1 , wherein the substrate is enabled to absorb the heat dissipated by the light source.
5 . The dipole antenna of claim 1 , wherein the substrate is coated with a reflective material to reflect impinging light rays.
6 . The dipole antenna of claim 1 , wherein each of the two sides comprises:
a forward path and a reverse path; and
a plurality of domains;
further comprises a plurality of capacitors, each of the plurality of capacitors electrically coupling a first domain in a first side of the two sides and a second domain in a second side of the two sides.
