TWD146648S - Roof antenna for motor vehicles - Google Patents

Abstract

[Item Usage] This new item is used on the roof of a car to receive or transmit electromagnetic wave signals, and is used as a decoration to match the overall shape of the car to make the car's appearance more prominent and visual. [Creative Features] This creation involves a decorative design of an antenna, specifically a new style of "car roof antenna" that is novel and beautiful, and is used to increase reflection and guidance when used for high-frequency radio waves to improve directional efficiency. The main appearance features of this new antenna include a thin, hollow, triangular main body with a much larger length direction ratio than width direction ratio and a relatively smaller height direction ratio. The main body includes a thin base, which forms a slightly V-shaped end at the rear end, and the width is gradually reduced and gradually rounded along the two sides thereof with a gradual curvature toward the front end, and the plane profile looks like a "shuttle", and the base is modified upward at an inclined angle to form a cone from the contour edge of the bottom end. In addition, the main body forms a gradually raised and gradually steep ridge from the front end vertex of the base along the central axis toward the rear end, and the rear end of the ridge drops sharply toward the rear end vertex of the base with a curvature, forming a concave end. When viewed from the front, the ridge forms a high "mountain" shape in the center of the cross-section of the main body, and the left and right sides are respectively modified into a round concave surface with a radius of curvature toward the top edge of the base. As a whole, a very special visual effect is formed. Such as the "automobile roof antenna" mentioned above. The overall construction method and dynamic composition can especially express the delicate visual beauty and specific connotation, the lines are stretched and smooth, the style is elegant and fresh, and it is a new style designer with rich visual beauty.
