Abstract:
A loop antenna, for use with a communication device, operating for exchanging energy at a radiation frequency, comprising,connection means having first and second conductors for conduction of electrical current, a radiation loop including a plurality of electrically conducting segments each having a segment length where, said segments are electrically connected in series between said first and second conductors for exchange of energy at the radiation frequency, said loop having an electrical length, Al that is proportional to the sum of segment lengths for each of said radiation segments, said segments are arrayed in three or more multiple divergent directions that form an irregular pattern and that tend to increase the loop antenna electrical length while permitting the overall outside dimensions of the antenna to fit within an antenna area of said communication device, said segments are arrayed in a pattern to form a loop where different segments connect at vertices and conduct electrical current in different directions near said vertices.
