Abstract
A capacitively coupled dipole antenna is coupled to a substrate such that a capacitative portion of the antenna spans a void in the substrate.
Claims25
A wireless device comprising:
- a first portion;
- a second portion;
- a third portion, the third portion coupled to the first portion and to the second portion;
- and
- a substrate, the substrate comprising at least one void, wherein the first portion, the second portion, and the third portion define a capacitively coupled dipole antenna, and wherein the antenna is coupled to the substrate.
2 more elements
A dipole antenna comprising:
- a first portion;
- a second portion, the first and second portion defining a capacitive area;
- a third portion, the third portion coupled to the first portion and to the second portion, the third portion defining an inductive area;
- and
- a substrate, the substrate defined by a periphery and a void within the periphery, wherein the first portion, the second portion, and the third portion define a capacitively coupled dipole antenna, and wherein the capacitively coupled dipole antenna is coupled to the substrate such that the capacitative area spans the void.
2 more elements
A system, comprising:
- a capacitively coupled dipole antenna, the antenna including a capacitative area;
- and
- a substrate, the substrate comprising a first void, wherein the antenna is coupled to the substrate, and wherein the capacitative area generally spans the void.
A capacitively coupled dipole antenna, comprising:
- capacitance means for creating a capacitance;
- and
- inductive means for creating an inductance.
A method for creating resonance in a resonant circuit, comprising the steps of:
- providing a first portion;
- providing a second portion;
- disposing the first and second portion to create a capacitive area;
- and
- coupling the third portion to the first portion and to the second portion to create an inductive area.
2 more elements
A system, comprising:
- a plurality of antennas, wherein at least two of the antennas each includes a capacitative area;
- and
- a substrate, the substrate comprising a plurality of voids, wherein the capacitative area of the at least two antennas generally spans respective ones of the plurality of voids.
