ABSTRACT:
Two separate microstrip antennas are interleaved in the same plane thereby occupying substantially the same area as a single antenna. Each antenna aperture produces two beams and the configuration for each antenna includes a single feed on each planar array which results in lowered overwater bias error. Each planar array antenna can have radiating arrays of different radiator spacing. Using forward firing arrays for one antenna and backward firing arrays for the other antenna, a radiated spacing is chosen for each interleaved antenna which results in temperature compensation in the along track direction.
