Abstract

Methods and devices allow omni-directional performance with high gain from a scanning phased array antenna (PAA). In some embodiments, the PAA includes at least 4 radiating antenna elements, each element fed one of only two phases separated by 180 degrees. In other embodiments, the PAA includes at least 4 radiating antenna elements, each element fed one of only four phases separated by 90 degrees. The two or four phases are controlled by a phase control device and obtained without use of phase shifters. The PAA is scanned to obtain an essentially omni-directional beam that provides a gain of at least a 6db. The PAA can be miniaturized and used in a cellular phone and other portable electronic devices.
