A millimeter wave imaging sensor includes a plurality of millimeter wave sensors disposed on one plane intersecting an incoming direction of millimeter waves emitted from a subject. Each of the plurality of millimeter wave sensors includes an antenna portion, a wave detection unit, a transmission path, and a shielding member. Adjacent millimeter wave sensors, among the plurality of millimeter wave sensors, are positioned according to outer peripheral shape of the shielding members of the adjacent millimeter wave sensors.

There is provided a method for designing a corrugated Fermi antenna having a broad-band and circular directivity required for receiving an image by using a wave of millimeter order. As a first step, an inflection point of the Fermi-Dirac function as a taper function of the Fermi antenna is changed so as to set the beam width of plane H to a beam width having a target directivity. After the beam width of the plane H is set to the target value, the aperture width of the Fermi antenna is changed so as to set the beam width of the plane E to a beam width having a target directivity. Thus, by adjusting the beam width values of the planes H and E independently from each other and matching them with the target values, it is possible to design a Fermi-antenna having a broad-band and circular directivity in a short time.
