Chip antenna with a feed arrangement to plural radiating elements including parasitic elements

A chip antenna comprises a first radiating element 100 connected to a first feed electrode 110 and a second radiating element 200, in the form of a feed pattern 210 and a planar meander radiating pattern 220, which is also connected to the first feed electrode 110. A second feed electrode 300 is connected to the first electrode 110 and electrically coupled to a first parasitic radiating element 400 and a second parasitic radiating element 500 which is electrically coupled to the first parasitic radiating element 400 and comprises a plurality of parasitic patterns. The radiating elements 100, 200, 400 and 500 provide a complex combination of planar and three dimensional conductive formations within a multi-layered chip structure. The first parasitic radiating element 400 is perpendicular to the feed electrode 200 and the parasitic element patterns of the element 500 are perpendicular to the first parasitic element 400. The number, size and spacing of the parasitic element patterns arranged to traverse the first parasitic element 400 may be adjusted to alter the central frequency, the impedance and the bandwidth of the said parasitic radiating elements 400, 500 as well as the mutual impedance arising between the radiating elements 100, 200, 400 and 500. The chip antenna provides a compact multi-band unit which can be mounted in GSM, DCS and BT terminals.
