Body worn antenna
First Claim
1. A wearable antenna for communicating between an external transceiver and a capsule inside the gastrointestinal tract of a user comprising:
- a printed circuit board comprising a first continuous planar conducting pattern printed directly on a first face and a second continuous planar conducting pattern printed directly on a second face of the printed circuit board,the first conducting pattern on the first face of the printed circuit board, comprising;
a) a conducting elongated bar across a center of the printed circuit board;
wherein the elongated bar is partially split to form two sides, forming a void between the sides of the elongated bar;
b) an identical main conducting transmission area on each side of the elongated bar;
c) a thin conducting line respectively connecting between each side of the elongated bar and the transmission area;
the second conducting pattern on the second face of the printed circuit board comprising;
a U shaped conductor having an elongated conducting area and an elongated conducting line;
wherein the U shaped conductor is positioned to serve as a balun for the conducting pattern on the first face; and
wherein the size of the printed circuit board is selected to be attachable to the lower back of the user and to transmit a signal having an ISM band frequency, wherein the U shaped conductor is shorted with the conducting elongated bar by via holes through the printed circuit board.
