<P>PROBLEM TO BE SOLVED: To provide a deployable phased-array antenna capable of enhancing a ratio of a projection area when housed and that when deployed, and performing phase correction electrically when deployed. <P>SOLUTION: A deployable array antenna consists of a substrate 10, an antenna element 20, a supporting body 30, a hinge 40, and a phase controller 50. The antenna element 20 is arranged on a plurality of substrates 10. The supporting body 30 is provided on at least one lateral face of the substrate 10, and extended so as to be projected from the substrate by a projection amount in multiples of a thickness of the substrate. The hinge 40 connects between adjacent substrates or between the substrate and the supporting body, and has a degree of rotation freedom of at least 180 degrees. The hinge 40 is arranged so as to be folded in a projection area substantially equal to the area of one substrate at the time of housing by combining with the supporting body 30. The phase controller 50 performs phase correction of phase errors generated caused by difference in a substrate height, depending on the projection amount of the supporting body. <P>COPYRIGHT: (C)2012,JPO&INPIT |
