雙頻段塊狀天線 Dual band block antenna

本發明涉及一種具有雙頻段的塊狀天線(Patch Antenna)。 The present invention relates to a patch antenna having a dual band.

圖1為現有塊狀天線的結構圖。現有塊狀天線1包括一面狀天線本體11、一介質12、一接地部13、一第一傳輸線14及一饋入點A。其中，面狀天線本體11、接地部13及第一傳輸線14均為導體。介質12設置在面狀天線本體11及接地部13之間，可為FR4(Flame Retardant 4)、空氣或陶瓷等材料。第一傳輸線14垂直該長方形的一邊，並相交于該邊的中點。 1 is a structural view of a conventional block antenna. The conventional block antenna 1 includes a planar antenna body 11, a medium 12, a grounding portion 13, a first transmission line 14, and a feed point A. The planar antenna body 11, the ground portion 13, and the first transmission line 14 are all conductors. The medium 12 is disposed between the planar antenna body 11 and the ground portion 13, and may be a material such as FR4 (Flame Retardant 4), air or ceramic. The first transmission line 14 is perpendicular to one side of the rectangle and intersects at a midpoint of the side.

圖2為現有塊狀天線的尺寸示意圖。通過第一傳輸線14的連接，天線共振頻率與天線本體11的關係為： 2 is a schematic view showing the size of a conventional block antenna. Through the connection of the first transmission line 14, the relationship between the antenna resonance frequency and the antenna body 11 is:

其中，ε r為介質12的介電係數，V為電磁波速度=3*108m/sec，L為與第一傳輸線14連接的長方形的一邊的鄰邊的邊長。因此，現有塊狀天線1通過第一傳輸線14的連接產生單一共振頻率，無法實現雙頻段的要求。 Here, ε r is the dielectric constant of the medium 12, V is the electromagnetic wave velocity=3*10 8 m/sec, and L is the side length of the adjacent side of the rectangular side connected to the first transmission line 14. Therefore, the existing bulk antenna 1 generates a single resonance frequency through the connection of the first transmission line 14, and the requirement of the dual frequency band cannot be achieved.

有鑒於此，有必要提供一種可以實現雙頻段要求的塊狀天線。 In view of this, it is necessary to provide a block antenna that can realize the dual band requirement.

本發明所提供了一種雙頻段塊狀天線，包括一面狀天線本體、一介質、一接地部、一第一傳輸線及一饋入點，其中，所述介質設置在所述面狀天線本體及所述接地部之間，所述面狀天線本體為一長度和寬度不同的長方形，所述第一傳輸線垂直該長方形的一邊，並與該邊相交，所述雙頻段塊狀天線還包括一第二傳輸線，垂直與該第一傳輸線垂直的長方形一邊的鄰邊，與該鄰邊相交點，並與該第一傳輸線連接於所述饋入點。 The present invention provides a dual-band block antenna, comprising a planar antenna body, a medium, a grounding portion, a first transmission line and a feeding point, wherein the medium is disposed on the planar antenna body and the Between the grounding portions, the planar antenna body is a rectangle having different lengths and widths, the first transmission line is perpendicular to one side of the rectangle and intersects the side, and the dual-band block antenna further includes a second And a transmission line, an adjacent side of the rectangular side perpendicular to the first transmission line, intersecting the adjacent side, and connected to the feeding point with the first transmission line.

圖3及圖4為本發明的雙頻段塊狀天線優選實施方式下的結構圖及天線共振尺寸示意圖。相對于現有塊狀天線1，雙頻段塊狀天線2中面狀天線本體11平面為一長度和寬度不相同的長方形，如圖4中所示邊長分別對應為L1和L2。雙頻段塊狀天線2還包括一第二傳輸線15，垂直與第一傳輸線14垂直的長方形一邊的鄰邊，並相交于該邊的中點，並與第一傳輸線14連接於饋入點A。通過饋入點A連接的第一傳輸線14使本發明雙頻段塊狀天線2具有對應於L1 的共振頻率f1為： 3 and FIG. 4 are a structural diagram and a resonant size diagram of an antenna in a preferred embodiment of the dual-band block antenna of the present invention. Compared with the existing block antenna 1, the plane of the planar antenna body 11 in the dual-band block antenna 2 is a rectangle having different lengths and widths, and the side lengths corresponding to L1 and L2 are respectively shown in FIG. The dual-band block antenna 2 further includes a second transmission line 15, which is perpendicular to the adjacent side of the rectangular side perpendicular to the first transmission line 14, and intersects at a midpoint of the side, and is connected to the first transmission line 14 to the feeding point A. The first transmission line 14 connected by the feed point A causes the dual-band block antenna 2 of the present invention to have a resonance frequency f1 corresponding to L1 as:

通過饋入點A連接的第二傳輸線15使本發明雙頻段塊狀天線2具有對應於L2的共振頻率f2為： The second transmission line 15 connected by the feed point A causes the dual-band bulk antenna 2 of the present invention to have a resonance frequency f2 corresponding to L2 as:

從而，由於該雙頻段塊狀天線2通過第一傳輸線14和第二傳輸線15的連接，且面狀天線本體11具有兩個不同長度的邊長L1及L2，則相應的具有兩個共振頻率。 Thus, since the dual-band bulk antenna 2 is connected by the first transmission line 14 and the second transmission line 15, and the planar antenna body 11 has two side lengths L1 and L2 of different lengths, there are corresponding two resonance frequencies.

圖5為本發明的雙頻段塊狀天線在優選實施方式下的電氣特性圖。圖中表示了本發明雙頻段塊狀天線2在不同的工作頻帶下的回波損耗(return loss)。從圖中可以看到當本發明雙頻段塊狀天線工作頻帶為0.8GHz及1.3GHz時，對應的回波損耗值為-20dB及-14dB，遠低於其他頻帶下的回波損耗值，因此，本發明雙頻段塊狀天線2通過第一傳輸線14及第二傳輸線15的雙路徑實現了對現有塊狀天線1的雙頻段的要求。 Figure 5 is a diagram showing electrical characteristics of a dual band block antenna of the present invention in a preferred embodiment. The figure shows the return loss of the dual-band block antenna 2 of the present invention at different operating frequency bands. It can be seen from the figure that when the operating band of the dual-band block antenna of the present invention is 0.8 GHz and 1.3 GHz, the corresponding return loss values are -20 dB and -14 dB, which is much lower than the return loss values in other frequency bands, so The dual-band block antenna 2 of the present invention realizes the dual-band requirement of the existing block antenna 1 through the dual path of the first transmission line 14 and the second transmission line 15.
