Embodiment 1

[0083] figure 1 It is a perspective view showing the configuration of an M-type antenna device according to Embodiment 1 of the present invention, figure 2 to represent figure 1 A perspective view of the basic structure of the M-type antenna unit 1 . exist figure 1 Among them, the M-type antenna device of Embodiment 1 is characterized in that it is configured to have two M-type antenna units 1, 2 on the ground conductor 11 having a feeder 12 in the middle, especially on the upper part of the M-type antenna unit 1. And the M-shaped antenna unit 2 is formed on the sides of both sides, so that it overlaps and shares the radiation conductor 4.

[0084] Such as figure 2 As shown, the basic structure of the M-type antenna unit 1 is that three radiation conductors 3, 4, 5 each having the same length are arranged on a rectangular ground conductor 11 made of a metal plate, so that they are parallel to each other and arranged in a prescribed manner. The upper ends of these res...

Embodiment 2

[0126] Figure 15 It is a perspective view showing the configuration of an M-type antenna device according to Embodiment 2 of the present invention. Compared with Embodiment 1, Embodiment 2 is characterized in that it further includes a matching conductor 8 composed of a straight conductor, and other structures are the same as Embodiment 1, and detailed description thereof will be omitted. Here, the matching conductor 8 is made of a wire, and is arranged in parallel with the radiation conductors 3, 4, 5, and one end of the matching conductor 8 is connected between the other end of the transmission conductor 6 connected to the radiation conductor 5 and the connection point P1 In addition, the other end of the matching conductor 8 is grounded.

[0127] The M-type antenna device according to the second embodiment configured as above has the following functions and effects in addition to the same functions and effects as those of the first embodiment. Specifically, in the M-type...

Embodiment 3

[0143] Figure 20 It is a perspective view showing the configuration of an M-type antenna device according to Embodiment 3 of the present invention. Compared with Embodiment 1, Embodiment 3 is characterized in that two M-type antenna elements 1 and 2 are provided in the dielectric 31 with the rectangular ground conductor 11b formed on the back and on the surface of the dielectric 31. Other configurations and implementations Same as Example 1, detailed description is omitted. Here, the radiation conductors 4a of the M-type antenna unit 1 and the M-type antenna unit 2 are formed inside the dielectric 31, the radiation conductors 3a, 5a of the M-type antenna unit 2 are formed on each side of the dielectric 31, and the transmission conductor 6a is formed on the upper surface of the dielectric 31 .

Abstract

An M-shaped antenna apparatus is constituted, so as to by provided with M-shaped antenna elements 1 and 2 respectively, having a first and a second resonance frequencies which are different from each other, a grounding conductor and a feeding portion. The M-shaped antenna element 1 is constituted so as to be provided with a transmission conductor 6, a radiation conductor 3 connected between one end of the conductor 6 and a grounding conductor 11, a radiation conductor 4 connected between an approximate middle portion of the conductor 6 and the portion 12 and a radiation conductor 5 connected between the other end of the conductor 6 and the conductor 11. The M-shaped antenna element 2 is constituted, so as to be provided a transmission conductor 6a, radiation conductors 3a, 4a and 5a in a manner similar to that of the element 1. In this case, the conductor 4a is connected to the partitions 1 and 2 via the conductor 4.

Description

[0001] This application is a divisional application with an application date of March 21, 2002, an application number of 02107786.X, and an invention title of "an antenna device". technical field [0002] The invention relates to an M-type antenna device equipped with at least two M-type antennas. Background technique [0003] 24 is a perspective view showing the configuration of a conventional antenna device capable of operating at multiple frequencies, Figure 25 It is an enlarged plan view showing the detailed configuration around the antenna unit 113 in FIG. 24 .
