Embodiment 200

[0043] It can be seen from the figure that the capacitively coupled ground transmission device 200 according to the present invention includes:

[0044] - With wire cover 2;

[0045] - a wired substrate 12; and

[0046] - a coupling block 8 arranged between the strip-line cover 2 and the strip-line substrate 12, wherein,

[0047] The strip line cover 2 and the coupling block 8 and the strip line substrate 12 and the coupling block 8 are coupled by capacitive coupling.

[0048] Compared with the traditional direct metal-to-metal connection, capacitive coupling between the strip line cover and the coupling block and the strip line substrate and the coupling block can ensure better PIM or passive intermodulation performance. Essential for ground transfer devices.

[0049] In addition, in an embodiment according to the present invention, the capacitively coupled ground transmission device 200 includes at least one films 6 and 9 to form electrical isolation between the strip line...

Abstract

The invention relates to capacitive-coupling grounding transmission devices (200, 300 and 400) and phase shifter network equipment. Each capacitive-coupling grounding transmission device comprises a stripline cover (2), a stripline substrate (12) and a coupling block (8), wherein the coupling block (8) is arranged between the stripline cover (2) and the stripline substrate (12); and the stripline cover (2) and the coupling block (8), and the stripline substrate (12) and the coupling block (8) are coupled in a capacitive coupling manner respectively. An appropriate capacitive coupling surface can balance a current between an inner cable and an outer braided cable, so that the same good voltage standing wave ratio and phase performance as those of traditional equipment can be achieved.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a capacitive coupling ground transmission device and a phase shifter network device. Background technique [0002] Nowadays, with the explosive development of the LTE network, there is a continuous demand for good and stable passive intermodulation performance (Passive Inter Modulation) of base station antennas. As we all know, in addition to the material quality of the base station antenna parts, the parts at the part connection are also a very important factor for the PIM performance of the base station antenna. In general, there is no PIM problem for joints that are not metal-to-metal joints. But most designs cannot avoid direct metal-to-metal connections. Therefore, the present invention seeks to design a device to replace today's direct metal-to-metal connections with the same S-parameter performance and reduced PIM risk. [0003] Generally, a base station ante...
