Abstract
Antenna arrays include first and second radiating elements, which are responsive to respective first and second hybrid radio frequency (RF) signals, and a power divider circuit. The power divider circuit is configured to generate the first and second hybrid RF signals as power-reduced combinations of first and second RF input signals received at input terminals thereof. For example, the first hybrid RF signal may be generated as a combination of a 70-90 percent energy contribution of the first RF input signal with a 0.26-2.7 percent energy contribution of the second RF input signal. Similarly, the second hybrid RF signal may be generated as a 70-90 percent energy contribution of the second RF input signal with a 0.26-2.7 percent energy contribution of the first RF input signal.
