Advantageously, the radiation pattern produced by the nonplanar complementary patch antenna is biased away from a normal axis of the tracking tag, and therefore can communicate efficiently with receivers when the tracking tag is oriented with its normal axis pointing away from the receivers.

A patch antenna includes a patch element and a ground conductor facing the patch element. The patch element is convex toward a side opposite to a side facing the ground conductor. Preferably, the patch element is convex while centering around at least one center line.
