Claim 0:
1. An antenna apparatus, comprising:
a main-reflection unit including a plurality of ribs formed to be deployable in a stored state in which the ribs are folded and a sheet body provided between a plurality of the ribs and configured to be capable of reflecting a radio wave radiated from a radiator and emitting the radio wave outside; and
a restriction member configured to restrict deployment of the plurality of ribs in the stored state, and release the restriction by operation of a restriction release member different from the main-reflection unit;
a sub-reflection unit that faces the main-reflection unit and includes a sub-reflector shaped and sized to reflect the radio wave radiated from the radiator to the main-reflection unit when in use;
wherein the sub-reflection unit is the restriction release member, and the sub-reflection unit is configured to be movable so as to be at a position in which the sub-reflector reflects the radio wave to the main-reflection unit when in use.
