Integrated circuit package including miniature antenna
First Claim
1. A device comprising:
- a substrate;
at least one chip and at least two sensors disposed in the substrate;
a first antenna disposed in a first area of the substrate, the first area arranged close to an edge of the substrate and having a longer side shorter than one-fifth of the longest free-space operating wavelength of the first antenna, wherein the first antenna comprises a conducting pattern, the perimeter of the conducting pattern defining a first curve comprising at least five segments, each of the at least five segments forming an angle with each adjacent segment in the curve, and wherein at least two of the angles are not equal and are defined respectively in the clockwise and counter-clockwise directions at opposite sides of the curve; and
a second antenna disposed in a second area of the substrate, the second area being arranged close to an edge of the substrate, wherein the second antenna comprises a conducting pattern, the perimeter of the conducting pattern defining a second curve, wherein the first and second areas do not enclose the at least one chip.

Abstract
The present invention relates to an integrated circuit package comprising at least one substrate, each substrate including at least one layer, at least one semiconductor die, at least one terminal, and an antenna located in the integrated circuit package, but not on said at least one semiconductor die. The conducting pattern comprises a curve having at least five sections or segments, at least three of the sections or segments being shorter than one-tenth of the longest free-space operating wavelength of the antenna, each of the five sections or segments forming a pair of angles with each adjacent segment or section, wherein the smaller angle of each of the four pairs of angles between sections or segments is less than 180° (i.e., no pair of sections or segments define a longer straight segment), wherein at least two of the angles are less than 115°, wherein at least two of the angles are not equal, and wherein the curve fits inside a rectangular area the longest edge of which is shorter than one-fifth of the longest free-space operating wavelength of the antenna.
