Abstract
A GPS antenna with anti-jam capabilities utilizes eight resonant loop radiator elements in a resonant exciter configuration to make available a primary and up to seven auxiliary antenna patterns usable with multi-pattern adaptive processing for anti-jam operation. Antennas as described enable desired radiation characteristics to be provided in a configuration of small size suitable for replacement of existing GPS aircraft antennas which lack anti-jam capabilities, in order to enable reliable GPS reception during airborne operations in the presence of interference or jamming. With enablement of multi-pattern adaptive processing, reduced-gain pattern notches or nulls may be employed to track and reduce the effect of incident signals which would otherwise jam or interfere with reception of GPS signals.
