Patent attributes
An antenna cover (1) for a radar (2) for a vehicle has a rectangular parallelepiped shape, having a flat cover top (10) that faces a microstrip antenna (21a, 21b) of the radar (2) and a sidewall (11) that covers the microstrip antenna (21a, 21b) sideways. The sidewall (11) is located out of the range where the electromagnetic waves to be received by the microstrip antenna (21a, 21b) are directly received. An inner face (11a) of the sidewall (11) is at a right angle to the cover top (10). An outer face (11b) of the sidewall (11) is at a constant angle θ larger than 0 degree but smaller than 90 degrees, to the inner face (11a) of the sidewall (11). The sidewall (11) is structured such that its thickness increases toward the side where the microstrip antenna (21a, 21b) is present.
