<p><P>PROBLEM TO BE SOLVED: To reduce leak-in and turn-in of transmission electric power from a transmission antenna into a reception antenna. <P>SOLUTION: A sheetlike electromagnetic wave absorbing body 8 with one face coated with a metal layer 7 is provided to partition an area for forming a transmission antenna 1 in antenna substrates (transmission antenna substrate 2, reception antenna substrate 4) from an area for forming a reception antenna 3 therein, and to close a space between the antenna substrates and a radome 6. One end face of the sheetlike electromagnetic wave absorbing body 8 with the one face coated with the metal layer 7 contacts with a grounding conductor layer 5. A radome portion 9 is secured between the other end face of the sheetlike electromagnetic wave absorbing body 8 with the one face coated with the metal layer 7 and an outer face of the radome 6. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
