Abstract
A reduced-size GPS antenna with anti-jam capabilities includes eight inclined monopole elements making available a primary and seven auxiliary antenna patterns usable with multi-pattern adaptive processing for anti-jam operation. An excitation network coupled to the eight monopole elements can be configured to provide the eight antenna patterns having quadrature characteristics with low mutual coupling. Bent monopoles or other elements may also be utilized. With availability of the primary and auxiliary patterns, multi-pattern adaptive processing can be employed during airborne operations to actively provide reduced-gain pattern notches or nulls to track incident angles of interference or jamming signals. In other embodiments selected combinations of less than all of the eight antenna patterns or other patterns may be employed.
