摘要： A first step sets a second inclination angle of a housing to an angle different from a reference housing angle by a limit angle; drives an actuator to set a first inclination angle to an angle different from a substrate inclination angle by the limit angle such that a beam axis is kept to be oriented to a specified direction; and measures, based on transmission and reception of a radar beam, first received power. A second step drives the actuator to set the first inclination angle to an angle located outside the adjustment range by a predetermined additional angle while the first inclination angle is maintained; and measures, based on transmission and reception of the radar beam, second received power. A third step determines whether a difference between the first received power and the second received power is greater than a predetermined determination threshold, and checks an operating state of the actuator based on a result of the determination.

摘要： Antenna assemblies are provided for receiving and transmitting radio frequency signals over an enhanced frequency band. An assembly includes an electrically conductive ground reference and a radiative element formed from an electrically conductive material and comprising an apex. The radiative element is electrically connected to an antenna feed at the apex and configured such that the radiative element lacks two-fold rotational symmetry around a first axis coinciding with the antenna feed. The radiative element extends such that a distance between the radiative element and the electrically conductive ground reference increases as a radial distance from the first axis along the radiative element increases.

摘要： A radiator coupled to an antenna patch disposed along a first end of the radiator, said patch disposed on an insulator. A ground plane is connected to the insulator and a radome is disposed opposite a second end of the radiator. The radome may have a region presenting a convex surface towards the radiator, and the radome has a second region presenting a concave surface towards the radiator. The first end of the conical radiator is the apex of the cone. A ground plane is included and a portion of the ground plane is a planar surface and another portion extends away from the planar portion towards the radome. Also disclosed is a method for forming a radiation pattern by shaping the radome to effectuate a predetermined radiation pattern using localized convex and concave surfaces positioned on the radome at different points in relation to the conical radiator.
