摘要: In order to achieve temperature compensation in a microstrip linear array, the array is periodically loaded by means of a plurality of open circuited stubs coupled to the main transmission line through tightly controlled gap dimensions to provide increasing shunt susceptance which compensates for the decease in shunt susceptance of the line as temperature increases.

摘要: In order to provide improved performance in a printed antenna, particularly for use in a Doppler navigation system, two pairs of linear arrays slanted at 45.degree. are utilized to obtain a beam shape which exhibits a degree of independence from over-water shift with the two sets of arrays constructed respectively as forward and backward firing arrays in order to compensate for frequency changes.

摘要: 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.

摘要: Separate receive and transmit interleaved arrays are distributed throughout a defined area. Each array is interconnected, at opposite ends thereof, to a feed line so that the receive and transmit antennas are each associated with four beams. Feed through connections are employed between receive feed lines and the receive arrays of the antenna thereby permitting the utilization of a microstrip structure.

摘要: A feed system for a microstrip or stripline antenna includes a serpentine traveling feed located in the plane of interleaved arrays along which a first signal propagates. A chain of crossover structures serves as a second traveling feed, extends in coplanar parallel spaced relation to the first feed, and carries a second propagated signal therealong. First and second ports of each structure connect the serpentine feed to a first group of arrays for coupling the first signal therebetween while third and fourth ports of each structure couple the second signal to a second set of arrays without significant interaction therebetween.
