Abstract
A single piece twin folded dipole antenna for transmitting and receiving electromagnetic signals is provided. The antenna includes a conductor extending in a V-shape at an angle of approximately 45 degrees adjacent to a ground plane. The conductor includes a feed section, a radiator input portion, and a radiating portion. The radiator input portion includes a first radiator input section and a second radiator input section whereby the radiator input sections are integrally formed with the radiating portion. The radiating portion includes a first radiating section and a second radiating section connected in parallel whereby each radiating section includes a fed dipole and a passive dipole.

A single piece twin folded dipole antenna for transmitting and receiving electromagnetic signals comprising:
- a V-shaped conductor whereby the length of the V extends at an angle of approximately 45 degrees adjacent a ground plane, the conductor comprising a feed section, a radiator input portion, and a radiating portion;
- the radiator input portion comprising a first radiator input section and a second radiator input section whereby the radiator input sections are integrally formed with the radiating portion;
- the radiating portion comprising a first radiating section and a second radiating section connected in parallel whereby each radiating section comprises a fed dipole and a passive dipole, the fed dipole being connected to the radiator input portion, the passive dipole being disposed in spaced relation to the fed dipole to form a gap;
- and
- wherein the feed section, the radiator input portion, and the radiating portion are formed from a sheet of material.
A method of making a single piece twin folded dipole antenna for transmitting and receiving electromagnetic signals comprising
- providing a conductor comprising three sections, a feed section, a radiator input portion, and a radiating portion whereby the radiator input portion is integrally formed with the radiating portion and the feed section, the radiating portion comprising a first radiating section and a second radiating section whereby each radiating section comprises a fed dipole and a passive dipole;
- extending the radiator input portion at an angle of approximately 45 degrees from a ground plane;
- forming the radiating portion into the first radiating section and the second radiating section where each radiating section is displaced from the ground plane;
- spacing the passive dipole from the fed dipole to form a gap;
- and
- connecting the first radiating section in parallel to the second radiating section.
