Embodiment Construction

[0044] Please refer to Figure 1A , Figure 1A It is a perspective view of an antenna device 10 according to an embodiment of the present invention. The antenna device 10 includes a base 100 , a first monopole antenna 102 , a second monopole antenna 104 and a decoupling circuit 106 . For the detailed operation, structure, and variation of the base 100, the first monopole antenna 102, and the second monopole antenna 104, please refer to the antenna device disclosed by the applicant in Taiwan Patent Application No. 100146526, and will not be repeated here. . Unlike the antenna assembly No. 100146526, Figure 1A The antenna device 10 improves the isolation between the first monopole antenna 102 and the second monopole antenna 104 through the decoupling circuit 106, thereby maintaining or improving the MIMO data throughput. At the same time, the decoupling circuit 106 does not need to greatly increase the horizontal plane area, so it does not occupy an additional area of ​​the an...

Abstract

The invention discloses a decoupling circuit and an antenna device. The decoupling circuit is used to improve the isolation between two monopole antennas. The two monopole antennas protrude from a base roughly symmetrically, and the two monopole antennas protrude from a base roughly symmetrically. A gap is formed between the antennas. The decoupling circuit includes a ground portion located on the base and electrically connected to a ground end; a connecting post, approximately perpendicular to the base, includes a first end electrically connected to the ground portion. , a second end extending toward the gap; a first branch extending from the second end of the connecting post to a first monopole antenna of the two monopole antennas; and a second branch extending from the connecting post The second end extends toward a second monopole antenna among the two monopole antennas.

Description

technical field [0001] The present invention refers to a decoupling circuit and an antenna device, in particular to a decoupling circuit and an antenna device that can effectively improve the isolation of a monopole antenna and help fully utilize a three-dimensional space. Background technique [0002] Electronic products with wireless communication functions transmit or receive radio waves through antennas to transmit or exchange radio signals, and then access wireless networks. Therefore, in order to allow users to access the wireless communication network more conveniently, the bandwidth of an ideal antenna should be increased as much as possible within the allowable range, while the size should be reduced as much as possible to match the trend of shrinking electronic products. In addition, with the continuous evolution of wireless communication technology, the number of antennas configured in electronic products may increase. For example, the Long Term Evolution (LTE) w...
