Abstract
Aircraft in an ECM environment require high-performance antenna arrays that are compact in size and easy to manufacture. Modern microstrip antennas are suitable candidates as elements for GPS arrays. It is shown that the small GPS polarimetric array has superior anti-jam capability compared with the conventional array. An N-element SGPA has 2N-2 degrees of freedom. It doubles the degrees of freedom as compared with the conventional array.
