Abstract:

PURPOSE: To prevent the generation of a dip in a received electric field due to the interference of a multiple reflection wave generated between a metallic surface on the front of a casing to which an antenna is fixed and window glass or the like existing in the front of the antenna with a direct incident wave transmitted through the window glass or the like.
