Stacked patch antenna with frequency band isolation

摘要

A stacked patch antenna (1) is constructed with separately fed patch elements (2, 3) coupled at their respective null points with a coaxial feed (9), the coaxial feed (9) feeding a first patch element (2), a portion of the first patch element (2) connecting its null point with a natural feed point to be fed by the coaxial feed (9), and a second patch element (3) being referenced to ground by the coaxial feed (9).
