Abstract
A capacitively loaded magnetic dipole antenna is provided with a portion that comprises a length that is longer than a straight line distance between a first end and a second end of the third portion such that antenna with a tower profile and/or smaller form factor is achieved.
Claims22
A wireless device comprising:
- a first portion;
- a second portion, the first and second portion disposed to effectuate a capacitive area;
- and
- a third portion, the third portion coupled to the first portion and to the second portion to effectuate an inductive area, wherein the third portion comprises a length having a first end and a second end, wherein the length is longer than a straight line distance between the first end and the second end, and wherein the first portion, the second portion, and the third portion define a capacitively coupled dipole antenna.
