Antenna module

摘要

An antenna module includes a center base and several antennas disposed around the center base. The center base has several extension legs extending from the center base, and each antenna extends from an end of the corresponding extension leg opposite to the center base, so as to form the antenna module symmetrically arranged around the center base. The type of the antenna may be a single-frequency antenna and a dual-frequency antenna. The antenna module is an integral structure formed by directly bending a single metal plate, thus greatly reducing the volume and the manufacturing cost of the antenna module. Moreover, with the design of the center base and a symmetrical antenna group, the antenna module is capable of receiving and transmitting signals with two or more frequency bands, thus greatly increasing the application range of the antenna module.

1. An antenna module, comprising:
a center base, having a first extension leg, a second extension leg, and a third extension leg, wherein the extension legs divide the perimeter of the center base into equal parts and extends from the center base, the center base having a first surface and a second surface opposite to the first surface, the first extension leg, the second extension leg, and the third extension leg each has a first extension portion and a second extension portion, the first extension portions are connected to the center base, and the first extension portion and the second extension portion of each extension leg form an L-shaped structure; a first antenna, a second antenna, and a third antenna, wherein the first antenna extends from an end of the first extension leg opposite to the center base, the second antenna extends from an end of the second extension leg opposite to the center base, the third antenna extends from an end of the third extension leg opposite to the center base, and the first antenna, the second antenna, and the third antenna each has a feed point, the feed points are used for receiving and transmitting at least one frequency band signal; and a plurality of grounding portions, wherein each of the grounding portions extend from the first extension portion, the first antenna, the second antenna, and the third antenna extend from the second extension portions of the first extension leg, the second extension leg, and the third extension leg respectively; wherein the center base, the first extension leg, the second extension leg, the third extension leg, the first antenna, the second antenna, the third antenna and the grounding portions are formed from a single piece of a metal sheet; and wherein an extending direction of the first extension portion of the first extension leg, an extending direction of the first extension portion of the second extension leg and an extending direction of the first extension portion of the third extension leg are orthogonal to the normal direction of the first surface, an extending direction of the first antenna, an extending direction of the second antenna and an extending direction of the third antenna are parallel to the normal direction of the first surface, and the first antenna, the second antenna and the third antenna extends along the normal direction of the first surface from the center base, the grounding portions vertically extend from the first extension portions respectively and are substantially a T-shaped structure.
