摘要：
A tag has antenna system includes three antenna portions. Each of the three antenna portions has a ½ dipole structure. A fourth antenna portion is shorted to the non-linear device. The antenna is tuned to an operating frequency by modifying the electrical lengths of one, two, or all three antenna portions. Preferably, the invention includes an inductive portion, such as a slot inductive portion. The antenna portions are configured in any desired form, such as being spiral or otherwise compacted, for particular operational parameters in a limited space.
