展開式メッシュアンテナ
Document Type and Number:
Japanese Patent JP6390949
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a desired correct electric field strength distribution matching the region to provide services and the serviced provided, by using the reflection mirror face normally becoming a uniform concave surface (parabolic face) by using a conductive mesh as a reflector of a modify mirror, in a foldout mesh antenna that is folded small in the rocket fairing.SOLUTION: A conductive mesh 40 composing the reflective surface of a large reflector on the orbit and a first wire network 10 sewn and fixed are connected by means of a second wire network 20 and a tie-wire 23 installed on the opposite side of the reflective surface, and an arbitrary part on the reflective surface side is connected with a third wire network 30 and a tie-wire 33 installed separately from the conductive mesh, so that the conductive mesh 40 can be pulled to any side out-of-plane of the reflective surface thus allowing provision of arbitrary irregularities.
