Abstract (en)

A multi-band antenna (300) includes a planar conductive layer (302) that comprises a conductive region (308) and a non-conductive region. The conductive region and the non-conductive region together define a first slot-strip structure (312), a second slot-strip structure (314) coupled to the first slot-strip structure, and a third slot-strip structure (316) coupled to the second slot-strip structure. The first slot-strip structure includes a signal feed portion (304). The second slot-strip structure includes a first signal grounding portion (306a). The third slot-strip structure includes a second signal grounding portion (306b).
