Optimization of a loop antenna geometry embedded in a wristband portion of a watch
First Claim
1. A wireless instrument including a wristband having a first and a second band portions connected to opposite edges of a casing, each of said first and second band portions having upper and lower surfaces, at least a first single loop antenna being embedded in said first band portion and extending between said corresponding upper and lower surfaces, said first single loop antenna being connected via first feeding lines through one edge of said casing to an antenna receiver inside said casing, said first single loop antenna and said first feeding lines defining a first radiating element, wherein said first feeding lines are arranged so as to be a negligible part of said antenna radiating element.

Abstract
The invention relates to a wireless instrument (1) including a wristband (2) having two band portions (2a, 2b) connected to opposite edges of a casing (3), each band portion having upper and lower surfaces (21,22). At least one single loop antenna (4a) is embedded in one band portion and extends between the corresponding upper and lower surfaces. This single loop antenna is connected via feeding lines (7) through one edge of the casing to an antenna receiver (5). The loop antenna and the feeding lines define a radiating element, wherein the feeding lines are arranged so as to be a negligible part of this antenna radiating element.
