INTEGRATED ANTENNA ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To enable a plurality of antennas to have proper directivity without making the constitution of the whole assembly large-sized nor complicated. SOLUTION: An in-vehicle integrated antenna assembly 1 has a GPS antenna 2 mounted at a nearly center in a square region 12 on a ground base board 4 and a VICS antenna 3 mounted in a rectangular region 13 on the ground base board 4 while a feed point 11 is disposed off the center of the rectangular region 13 in short side directions. Symmetrical directivity such that a zenithal gain is large and an elevation angle is small can be obtained as the directivity of the GPS antenna 2, and directivity which is asymmetrical at short sides of the rectangular region 13 or directivity which is asymmetrical in at long sides of the rectangular region 13 can be obtained as the directivity of the VICS antenna 3.
