1. A radiation detection apparatus, comprising:
a housing that includes an incidence surface and a back surface located on the opposite side of the incidence surface;
a sensor panel within the housing, the sensor panel being configured to convert radiation incident from the incidence surface into an electrical signal;
a conductive plate within the housing, and which extends in a direction intersecting with a normal to the incidence surface; and
an antenna element within the housing, wherein
the conductive plate is located between the sensor panel and the back surface,
the antenna element is located between the conductive plate and the back surface in a region overlapping the conductive plate when viewed along a direction of incidence of the radiation,
the antenna element includes a portion having a gap with the conductive plate and extending in the direction intersecting with the normal to the incidence surface, and
the conductive plate and the antenna element are electrically connected.
