Claim Text:
1. A mobile transmit diversity device comprising: a first power amplifier; a first matching circuit configured to receive and mediate at least a phase of the first signal from the first power amplifier; a first antenna configured to receive and radiate the first signal mediated by the first matching circuit; a second power amplifier; a second matching circuit configured to receive and mediate at least a phase of the second signal from the second power amplifier; a second antenna configured to receive and radiate the second signal mediated by the second matching circuit; wherein the first and second antennae are configured to be within each other's near field such that the radiated signals from each of the first and second antennae are coupled by near-field wireless coupling; and wherein each of the first and second matching circuits include a network topology comprising a plurality of impedance components, wherein impedance values of the impedance components are chosen, based on the coupled signals, to produce reflection coefficients and VSWR values that reduce TRP at a phase setting that produces a worst case SAR by the coupled signals among the antennae.
