Abstract
An architecture for providing a low cost, high performance antenna for small devices In particular, a rotatable antenna that having three antenna elements; a primary element consisting of a radiating element and swiveling cylindrical head, a secondary element that consists of a feeding cylindrical pin attached vertically to an electronic device main board, and a third element that consists of a plastic part over-molding the secondary element to permit electromagnetic coupling accuracy between the primary and secondary elements.
Claims10
An rotatable antenna, comprising:
- a first element electrically coupled to a printed circuit board, where the first element comprises a first cylindrical portion;
- a second element having a second cylindrical portion, said second cylindrical portion having a cavity for receiving said first cylindrical portion such that said second element rotates around an axis of said first element;
- and
- a third element immovably fixed to a portion of said first element and movably fixed to a portion of said second cylindrical portion such that said second cylindrical portion is prevented from touching said first cylindrical portion.
1 more element
An apparatus comprising:
- a printed circuit board;
- an enclosure for enclosing at least a portion of said printed circuit board, said enclosure having a circular aperture over a portion of said printed circuit board;
- a cylindrical antenna element affixed to the printed circuit board such that an axis of said cylindrical antenna element is orthogonal to a plane of said printed circuit board, said axis also being in alignment with said aperture;
- and
- a radiating antenna element having a cylindrical portion, wherein said cylindrical portion is positioned over a portion of said cylindrical antenna element, and wherein said cylindrical portion is positioned within said aperture of said enclosure such that cylindrical portion is movably retained by said enclosure such that a gap is maintained between said cylindrical antenna element and said cylindrical portion.
