Abstract: An antenna comprises a ground pattern, and a planar element that is fed and equipped with a cut-out portion provided from the farthest edge portion formed from the feed position toward the ground pattern side, and the ground pattern and the planar element are juxtaposed with each other.

Abstract: Antenna systems for handheld wireless communication devices (100) that comprise a first unbalanced feed antenna (112, 718, 802, 1204, 1812) and a second balanced feed antenna dipole antenna (202, 716, 804, 1202, 1802) that are located next to a ground structure (116, 810, 1210, 1824) for the handheld wireless communication devices are provided. The balanced feed dipole antenna and the unbalanced feed antenna exhibit disparate spatial-polarization patterns which are suitable for use with a MIMO transceiver, and the decorrelation of signals received by the two antennas is preserved due to a low level of coupling through the ground structure, which is due, in part, to differences in the symmetry properties of current patterns in the ground structure that are associated with the operation of the two antennas. The two antennas can also be used in a transceiver (629) that uses separate antennas to receive and transmit.
