Problems solved by technology
In the millimeter wave frequency band, the traditional PCB process has obvious disadvantages in package integration and miniaturization. The surface wave effect and the loss of the microstrip line at the bend and discontinuity cause the efficiency of the microstrip patch antenna to decrease.
LTCC is a relatively new packaging technology, but the high dielectric constant of the LTCC medium causes the antenna to be greatly affected by surface waves in the millimeter wave and terahertz frequency bands, resulting in problems such as decreased efficiency of the antenna and distortion of the pattern
Diffusion bonding technique (Meta Diffusion BondingTechenique, MDBT) is suitable for complex metal cavity structure, but its processing accuracy is limited by copper foil etching accuracy and poor
The Micro-electromechanical Systems (MEMS) process is to metallize the surface of silicon substrates with different thicknesses of corresponding shapes, and then perform interlayer metal bonding to form complex inner cavity structures. The process is characterized by the ability to achieve micron-scale High-precision metal inner cavity structure, but its processing cost makes it difficult to apply to complex structural design

Description
technical field [0001] The present invention relates to the field of communications, in particular to a 5G millimeter wave antenna and a manufacturing method thereof. [0002] networks Background technique [0003] The fifth generation mobile communication system (5th generation mobile networks, 5G for short) is getting closer and closer to official commercial use (2020). Every stage of mobile communication system development requires wider spectrum resources, and its spectrum resources are mainly concentrated in frequency bands below 6 GHz. At the same time, the wireless smart devices of the Internet of Things use frequency bands below 6 GHz, which causes spectrum resource shortage. A large number of devices are concentrated in low-frequency spectrum resources, causing serious interference sources in the electromagnetic environment, making it difficult to implement high-speed mobile communication systems. The millimeter wave frequency band has a pure electromagnetic envi...
