发明名称 Three-Element Antenna Array for Wireless Handsets
摘要 A multiple antenna beam steering device includes three-element array, which are controlled to increase power reception in the direction of the desired signal while simultaneously minimizing signal reception in one or more directions of interference, using selective weighting of received signals, and specified summation stages to produce combined array factors that are used to form a beam pattern that is both maximized in at least one signal direction and minimized in at least one interference direction.

主权项 1. A wireless receiver device comprising: a three-element antenna array comprising a first antenna element, a second antenna element, and a third antenna element, where each is a wire dipole antenna; and a beamformer controller coupled to the three-element antenna array and comprising a separate receive signal path for each of the first antenna element, the second antenna element, and the third antenna element, wherein the receive signal path for the first antenna element includes a first weighting element to produce a first weighted receive signal and the receive signal path of the second antenna element includes a second weighting element to produce a second weighted receive signal, and wherein the receive signal path for the third antenna element is unweighted relative to the other receive signal paths to produce an unweighted receive signal, the beamformer controller further comprising (i) a first antenna weighting factor stage configured to determine a minimization antenna weighting factor from the first weighted receive signal and the unweighted receive signal and (ii) a second antenna factor stage configured to determine a maximization antenna weighting factor from the second weighted receive signal and the unweighted received signal, the beamformer controller further comprising a combined array factor stage configured to produce a combined array factor from the minimization antenna factor and the maximization antenna factor, andan array factor stage to produce a combined array factor from the first summing element and the second summing element,wherein the array factor stage is coupled to a transmitter or receiver stage for multiplying the combined array factor with a single element radiation pattern to form a beam pattern that is both maximized in at least one signal direction and minimized in at least one interference direction.
