PROBLEM TO BE SOLVED: To provide an antenna element arrangement structure and an electric wave reception processing apparatus, which cover a wide reception range while sufficiently securing an antenna gain. SOLUTION: An antenna 4 comprises a support member 1 and five antenna elements 2. As the antenna elements 2, what is called patch antennas (flat antennas) are used. The support member 1 is formed into a rectangular parallelepiped shape and has one antenna element 2 arranged on each of two side surfaces thereof opposite to each other, has one antenna element 2 arranged on the upper surface thereof, and has two antenna elements 2 and 2 arranged on the lower surface thereof. Central axes in a directional range of respective antenna elements are present in one plane approximately, and angles formed by the central axes are set to about 72°. COPYRIGHT: (C)2005,JPO&NCIPI
