Abstract

An antenna for receiving and transmitting radio signals, including a reflective unit, comprising a central reflective element; and a plurality of peripheral reflective elements, enclosing the central reflective element to form a frustum structure; and at least one radiation unit, disposed above the central reflective element; where the reflective unit is electrically isolated from the at least one radiation unit.

First claim

What is claimed is:

1 . An antenna for receiving and transmitting radio signals, comprising:
a reflective unit, comprising:
a central reflective element; and
a plurality of peripheral reflective elements, enclosing the central reflective element to form a frustum structure; and
at least one radiation unit, disposed above the central reflective element; wherein the reflective unit is electrically isolated from the at least one radiation unit.

2 . The antenna of claim 1 , further comprising a reflective plate disposed above the at least one radiation unit, wherein a shape of the reflective plate has symmetry.

3 . The antenna of claim 2 , wherein a distance between the central reflective element and the reflective plate is less than one quarter of an operating wavelength.

4 . The antenna of claim 2 , wherein the reflective plate is a circle or a regular polygon, wherein a number of vertices of the regular polygon is a multiple of 4 .

5 . The antenna of claim 1 , wherein the frustum structure has symmetry, and each of the plurality of peripheral reflective elements comprises:
a conductor base plate; at least one conductor patch; at least one via, wherein the at least one conductor patch is connected to the conductor base plate with the at least one via respectively to form a mushroom-type structure providing magnetic conductor reflection effects; and a spacer layer, surrounding the at least one via.

6 . The antenna of claim 5 , wherein the conductor base plate has a shape substantially conforming to a trapezoid, and a shape of the at least one conductor patch is similar to the shape of the conductor base plate.

7 . The antenna of claim 1 , wherein the at least one radiation unit comprises at least one conductor plate, and each of the at least one conductor plate comprises:
a main section; and a feed-in point, disposed on the main section.

8 . The antenna of claim 7 , wherein the main section of a first conductor plate of the at least one conductor plate and the main section of a second conductor plate of the at least one conductor plate form a bishop hat dipole antenna, and the first conductor plate and the second conductor plate have symmetry.

9 . The antenna of claim 8 , wherein each of the at least one conductor plate further comprises a first arm section, the first arm section is not coplanar to the main section, and an end of the first arm section is connected to an end of the main section.

10 . The antenna of claim 9 , wherein each of the at least one conductor plate further comprises a second arm section, the second arm section is not coplanar to the main section, an end of the second arm section is connected to the main section, and the end of the second arm section is separated from the end of the main section by a distance.

11 . A complex antenna for receiving and transmitting radio signals, comprising a plurality of antennas, each of the plurality of antennas comprising:
a reflective unit, comprising:
a central reflective element; and
a plurality of peripheral reflective elements, enclosing the central reflective element to form a frustum structure; and
at least one radiation unit, disposed above the central reflective element; wherein the reflective unit is electrically isolated from the at least one radiation unit.

12 . The complex antenna of claim 11 , each of the plurality of antennas further comprising a reflective plate disposed above the at least one radiation unit, wherein a shape of the reflective plate has symmetry.

13 . The complex antenna of claim 12 , wherein a distance between the central reflective element and the reflective plate is less than one quarter of an operating wavelength.

14 . The complex antenna of claim 12 , wherein the reflective plate is a circle or a regular polygon, wherein a number of vertices of the regular polygon is a multiple of 4.

15 . The complex antenna of claim 11 , wherein the frustum structure has symmetry, and each of the plurality of peripheral reflective elements comprises:
a conductor base plate; at least one conductor patch; at least one via, wherein the at least one conductor patch is connected to the conductor base plate with the at least one via respectively to form a mushroom-type structure providing magnetic conductor reflection effects; and a spacer layer, surrounding the at least one via.

16 . The complex antenna of claim 15 , wherein the conductor base plate has a shape substantially conforming to a trapezoid, and a shape of the at least one conductor patch is similar to the shape of the conductor base plate.

17 . The complex antenna of claim 11 , wherein the at least one radiation unit comprises at least one conductor plate, and each of the at least one conductor plate comprises:
a main section; and a feed-in point, disposed on the main section.

18 . The complex antenna of claim 17 , wherein the main section of a first conductor plate of the at least one conductor plate and the main section of a second conductor plate of the at least one conductor plate form a bishop hat dipole antenna, and the first conductor plate and the second conductor plate have symmetry.

19 . The complex antenna of claim 18 , wherein each of the at least one conductor plate further comprises a first arm section, the first arm section is not coplanar to the main section, and an end of the first arm section is connected to an end of the main section.

20 . The complex antenna of claim 19 , wherein each of the at least one conductor plate further comprises a second arm section, the second arm section is not coplanar to the main section, an end of the second arm section is connected to the main section, and the end of the second arm section is separated from the end of the main section by a distance.
