Abstract
In [1] a new antenna design has been proposed. A physical antenna model revealed, unexpectedly, that contacts develop between panels of adjacent wings of the reflector during deployment. Due to the contacts, additional constraints are imposed on the motion, reducing the mobility to zero and thus, requiring some deformation for deployment. This paper adresses foldable structures of this kind. They can be modelled in terms of a multibody system, the mobility of which is reduced to zero due to the occurrence of unilateral contact.
