Abstract

Certain embodiments for antenna geometry for multiple antenna handsets may include receiving RF signals via a patch antenna coupled to a signal processing circuitry within a mobile terminal. The signal processing circuitry may process the RF signals, comprising at least one of a plurality of polarizations that are received by the patch antenna. The patch antenna may be a dual-polarized antenna, and may comprise a plurality of ports. RF signals at a first of the plurality of ports may be orthogonally polarized with respect to RF signals at a second of the plurality of ports. The patch antenna may be optimized to receive multiple RF bands. Each of the multiple RF bands may be communicated via different ports to be processed.
