Abstract
A multiband comformed-slotted-folded dipole antenna (200) having a unitary conformed shape conductor conforming to an internal communication device configuration (400). The antenna can include a folded dipole (203, 205, 209, 206, 204) forming a part of the unitary conformed shape and having a first portion (212 or 213) forming at least one slot in a slotted plane (220) and a second portion (210 or 211) forming at least one slot in a second plane (230) substantially perpendicular to the slotted plane. The at least one slot in the second plane controls high band antenna resonance and a length (209) of a metal portion in the slotted plane controls lower band resonance. Additional embodiments are disclosed.
Claims20
A multiband comformed-slotted-folded dipole antenna, comprising:
- a unitary conformed shape conductor conforming to an internal communication device configuration;
- a folded dipole forming a part of the unitary conformed shape and having a first portion forming at least one slot in a slotted plane and a second portion forming at least one slot in a second plane substantially perpendicular to the slotted plane;
- and
- wherein the at least one slot in the second plane controls high band antenna resonance and a length of a metal portion in the slotted plane controls lower band resonance.
An antenna, comprising:
- a conformed slotted dipole antenna element having first antenna elements in a slotted plane and second antenna elements in a second plane, wherein the slotted plane is substantially orthogonal to the second plane;
- a first slot and a second slot in the second plane that controls a high band resonance when the slots are tuned;
- and
- a conductive line in the slotted plane having a length that controls a low band resonance.
An antenna, comprising:
- a substantially T-shaped slot in a slotted plane forming a low band controlling line portion coplanar and above the T-shaped slot and a high band controlling line portion coplanar and below a cross bar of the T-shaped slot;
- a conductive line that is non-coplanar with the slotted plane and forms a slot having a gap between the slotted plane and the conductive line, wherein the gap further controls a high band resonance of the antenna.
