Patent abstract
Controlled phase shift in the operation of an RF antenna element is achieved by selectively choosing between different modes of antenna element resonance. Additional phase control resolution is achieved by combining this with other types of phase shifters. Such phase shifters are especially useful within a phased array of RF antenna radiator elements.
