Abstract: PURPOSE:To quickly restart reception even in the case of the occurrence of short-time shielding by performing the tracking control at the time when the cosine component of the phase difference of an antenna exceeds a specific threshold. CONSTITUTION:The allowable minimum value larger than the peak value of the side lobe of the cosine component of the phase difference is denoted as a threshold P1, and tracking control is performed when the cosine component exceeds the threshold p1, and thereby, tracking control is difficult to miss even if the reception signal level is reduced by the weather difference. After tracking control is started, a reception signal level A is obtained by square averages of the cosine component and the sine component. The allowable minimum value which is larger than the peak value of the side lobe of the level A in the range of -180 deg.

Abstract: PROBLEM TO BE SOLVED: To provide a roadside communication antenna controller capable of maintaining the quality of communication with a traveling object such as a vehicle. SOLUTION: The roadside communication antenna controller which controls a roadside communication antenna for communication with the vehicle acquires position information on the vehicle establishing communication with the roadside communication antenna, estimates a communication establishment zone that the roadside communication antenna forms based upon the acquired position information. The tilt angle of an antenna beam is made small so as to make the communication establishment zone wide when the estimated communication establishment zone has a too short distance shorter for its design value, and the tilt angle θ is or large so as to make the communication establishment zone narrow when the estimated communication establishment zone has a too long distance for its design value.
