摘要： PROBLEM TO BE SOLVED: To control a directivity control device in response to environmental characteristics such as density of high-rise buildings. SOLUTION: The directivity control device 106 switches or synthesizes received signals by two antennas A1 and A2 with a switch 110 or a synthesizer 120. The elevation angle of the antennas A1 and A2 are directly switched by elevation angle switching devices A1C and A2C separately. When a ratio of height H of a building to road width W is larger than a first threshold H th1 and a position of transmitting point is in the right or left region, a directivity of the directive antenna 1 is controlled to have a high elevation angle to be perpendicular to the road leftward or rightward. In other cases, the directivity is a low elevation angle and is horizontally changed by electric wave's arrival angle. In suburbs, the directivity is controlled to be a low elevation angle in the direction of transmitting point. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent distortion in the directivity of a GPS (global positioning system) without using a horizontally large conductor board.
SOLUTION: A board 4 has two slots 4b which elongate a current path on the board 4 as in a case where a horizontally large board is used. As a result, when metallic members such as a fire wall, a reinforcement, audio unit or the like, are arranged on the back of the board 4, current flowing at the end of the board 4 is reduced even when an electromotive force is generated on the board 4 by the radio waves from a GPS satellite that are reflected on the metallic members. Less current at the board end leads to less radio waves radiated from it on the basis of the currents, thus resulting in less radio waves radiated from the board end to come into a radiation element 1.
