摘要： Examples of techniques for antenna ground and feed swapping in handheld applications are described. A condition with respect to wireless communication of a handheld apparatus having one or more antennas may be detected in determining whether to operate the handheld apparatus in a first mode or a second mode of wireless communication. In response to a determination to operate the handheld apparatus in the first mode, a first feeding port and one or more first shorting ports may be electrically connected to at least one antenna of the one or more antennas each disposed adjacent a first distal end of the handheld apparatus. Alternatively, in response to a determination to operate the handheld apparatus in the second mode, a second feeding port and one or more second shorting ports may be electrically connected to at least one antenna or another antenna of the one or more antennas.

摘要： A multi-band antenna array includes a plurality of first antennas for resonating at a first band, and a plurality of second antennas for resonating at a second band. A frequency of the second band is higher than a frequency of the first band. Locations of the plurality of first antennas project to a plurality of grid-one positions on a surface; locations of the plurality of second antennas project to a plurality of grid-two positions on the surface. Among the grid-one positions, a second grid-one position is nearest to a first grid-one position by a first distance along a first direction. Among the grid-two positions, a first grid-two position and a second grid-two position are closest two to the first grid-one position. The first and second grid-two positions are separated by a second distance along a second direction; and, the first direction and the second direction are nonparallel.
