Abstract

The necessity of the research on the technology against strong interference with the same frequency of the GPS is first proved through calculation, the operating principle and process of the adaptive nulling antenna (ANA) is described and demonstrated. The characteristic of the power inverted (PI) algorithm is summarized synthetically. Two feasible antenna array forms are developed, in which is a 4-element circular array whose pattern has been calculated and the other is a rectangular microstrip antenna, the theory of which is unveiled. Finally, some problems and tendencies that are considered during the practical design are presented
