Abstract

A wireless electronic device includes dual radiating antennas, with each of the dual radiating antennas including a first radiating element and a second radiating element. The wireless electronic device includes power dividers, a respective one of which is associated with a respective one of the dual radiating antennas and is configured to divide the power of a signal into a first portion of the power and a second portion of the power. The first portion of the power is applied to a respective first radiating element and the second portion of the power is applied to the respective second radiating element. The wireless electronic device is configured to resonate at a resonant frequency corresponding to the first radiating element and/or the second radiating element of at least one of the plurality of dual radiating antennas when excited by a signal transmitted by at least one of the plurality of dual radiating antennas.
