Abstract:
1. A planar circuit housing for containing a planar circuit, comprising: a support portion for supporting only surrounding edges of the planar circuit, the support portion being provided only on a housing internal surface that is substantially perpendicular to the planar circuit substrate; an upper cavity in the housing above the planar circuit; and a lower cavity in the housing below the planar circuit, the lower cavity having the same sizes as the upper cavity in directions parallel with the planar circuit substrate, wherein internal surfaces of the housing have no convexity or concavity except for the support portion; and the housing is made entirely of a solid conductor and is separated into at least two conductor body parts, the at least two conductor body parts having contacting conductor faces, and the contacting conductor faces consist of only a single curved plane all around the planar circuit substrate so as to prevent penetration of electromagnetic waves.
