Abstract: A method of sending and receiving dual-polarization, millimeter-wave signals to and from a mobile device having a top surface, a bottom surface, and an edge surface, includes: radiating energy, in a millimeter-wave frequency band, from a first radiator outwardly from the edge surface with a first polarization; receiving, via the first radiator, energy in the millimeter-wave frequency band with the first polarization; radiating energy, in the millimeter-wave frequency band, from a second radiator outwardly from the edge surface with a second polarization substantially perpendicular to the first polarization, the second radiator being disposed between the first radiator and the top surface or the bottom surface, or a combination thereof; and receiving, via the second radiator, energy in the millimeter-wave frequency band with the second polarization.

Abstract: The present example provides a co-location insensitive multi-band antenna. The antenna may be co-located with an antenna operated at another band and tends to reject interference from that antenna. The co-location insensitive multi-band antenna tends to provide a compact design that may be printed on a printed wiring board, on a case of a radio, such as a cellular telephone or may be self supporting. In general, the desired in band performance and out of band signal rejection may be achieved by a meander line coupled to a upper band patch. The meander line tends to provide a good lower band match, and the upper band patch tends to provide a good high band match, or resonance. The upper band patch also tends to cause a sharp roll off in return loss before the high band, that tends to reject frequencies from a co-located antenna transmitting below the high band.

Abstract: Co-location insensitive multi-band antenna. The present example provides a co-location insensitive multi-band antenna. The antenna may be co-located with an antenna operated at another band and tends to reject interference from that antenna. The co-location insensitive multi-band antenna tends to provide a compact design that may be printed on a printed wiring board (“PWB”), on a case of a radio, such as a cellular telephone or may be self supporting. In general, the desired in band performance and out of band signal rejection may be achieved by a meander line coupled to a upper band patch. The meander line tends to provide a good lower bad match, and the upper band patch tends to provide a good high bad match, or resonance. The upper band patch also tends to cause a sharp roll off in return loss before the high band, that tends to reject frequencies from a co-located antenna transmitting below the high band.

Abstract: A wireless communication device is provided with a multipart case, having electrical interfaces that encourage the flow of radiation frequency ground current between case sections. The multipart case has a first planar groundplane section and a second planar groundplane section. For example, the multipart case design may be a slider, double slider, multiple hinge, flip, or swivel case. The second planar groundplane is substantially coplanar with the first groundplane in a case open position, and substantially bi-planar with the first groundplane in a case closed position. The wireless device also includes an antenna located adjacent the second groundplane section first end. A first and a second interface electrically connect the first groundplane section to the second groundplane section second end (the end opposite the antenna).
