Interferometric antenna array for wireless devices
First Claim
1. An interferometric antenna array for use with a wireless communications device in reducing electromagnetic energy in a region proximate to the antenna array, comprising:
- two radiating elements formed of conducting material and adapted for use with a wireless communications device and arranged side-by-side separated by a distance;
a power splitting means coupled to the wireless communications device for dividing a signal from a feed of the wireless communications device into two split signals;
a phase shifting means coupled to the two radiating elements and to the power splitting means for creating a phase difference between the two split signals;
wherein each of the two radiating elements is fed by one of the two phase-shifted split signals; and
wherein the wave pattern formed by the electromagnetic energy emitted from the radiating elements includes a spatial null proximate to the antenna array.

Abstract
An interferometric antenna array for use with a wireless communications device in reducing electromagnetic energy in a region proximate to the antenna array. The antenna array comprises two or more radiating elements coupled through circuitry to the wireless communications device. The circuitry operates to appropriately divide a signal from the communications device into a plurality of signals and to phase-shift the plurality of signals such that the electromagnetic wave pattern formed proximate to the antenna array by the two or more radiating elements, which are fed by the phase-shifted plurality od signals, includes a spatial null. The spatial null is located at a region where sensitive electronic equipment, or some portion of a user of the communications device is also located.
