Abstract
An antenna apparatus has a first antenna branch and a second antenna branch. Both the first and the second antenna branch are in the form of a conductor loop which is not closed, and the first antenna branch is arranged at a distance from the second antenna branch in a direction which is substantially at right angles to the surface bounded by the respective conductor loop, such that the first loop direction, which is defined from the foot point to the free end of the first antenna branch, is arranged in the opposite direction to the second loop direction, which is defined from the foot point to the free end of the second antenna branch.
Claims21
An antenna apparatus, comprising:
- a first antenna branch formed in a non-closed conductor loop with a foot point and a free end;
- a second antenna branch formed in a non-closed conductor loop with a foot point and a free end;
- and
- a first foot section and a second foot section cooperating to keep said first antenna branch a fixed distance away from said second antenna branch;
- said conductor loop of said first and second antenna branches each delimiting a plane and said first antenna branch being spaced apart from said second antenna branch in a direction substantially perpendicular to the planes delimited by said conductor loop, and defining a first loop direction, defined from said foot point to said free end of said first antenna branch, opposite a second loop direction, defined from said foot point to said free end of said second antenna branch.
