MULTI-BAND LOADED ANTENNA

摘要

A planar antenna for wireless information transfer can include a planar loading portion electrically (450) coupled to a driven node of a wireless communication circuit, and a folded conductive strip portion coupled to the planar loading portion, the folded conductive strip portion comprising at least two segments (460b, 460d) laterally offset from each other and at least partially laterally overlapping with each other. The planar loading portion can be configured to establish a specified bandwidth of a second operating frequency range, leaving a first specified operating frequency range substantially unchanged.
