Problems solved by technology
[0006] In the millimeter wave frequency band, on the one hand, the metal lines of the microstrip antenna have become very fine, and the metal must be patterned by the conventional photolithography technology in the microelectronics process; on the other hand, in order to reduce loss, improve efficiency and gain Usually tend to choose a thinner substrate, and plastic materials such as polyethylene or polypropylene are soft, so the prior art cannot use the photolithography technology in the microelectronics process to directly fine-tune the metal film with the above-mentioned plastic thin layer as the substrate. processing; in addition, they are all difficult-to-bond materials, which are difficult to bond directly with metal

The invention discloses a millimeter wave micro-strip antenna and a manufacturing method thereof, relating to the technical fields of millimeter wave wireless communication and antennae. The millimeter wave micro-strip antenna comprises an antenna substrate (1) and a graphic metal film (8), wherein the antenna substrate (1) comprises a printed circuit copper-clad plate (4), lower layer epoxy resin (5), a polypropylene or polyethylene plastic layer (6) and upper layer epoxy resin (7) which are arranged from bottom to top; the graphic metal film (8) is positioned on the surface of the lower layer epoxy resin (5); and the printed circuit copper-clad plate (4) comprises an epoxy resin substrate (2) and a copper foil (3). In the invention, the substrate of the millimeter wave micro-strip antenna is manufactured by taking the printed circuit copper-clad plate which consists of the resin substrate and the copper foil on the surface of the resin substrate as well as a layer of common plastic as main bodies, so that the radiance efficiency and signal gain of the micro-strip antenna can be increased, and the cost of the antenna can be lowered.
Description
technical field [0001] The invention relates to the technical field of millimeter-wave wireless communication and antennas, and in particular, to a millimeter-wave microstrip antenna and a preparation method thereof. Background technique [0002] Miniaturization, integration, and broadbandization have always been the development directions of wireless mobile communication systems, and the expansion of the frequency band used to the millimeter wave frequency band is an inevitable trend of future development. [0003] As the frequency band increases, the size of the antenna will decrease proportionally. Due to the advantages of small size, light weight, low profile, and easy conformation with the carrier, the microstrip antenna will play a more important role in wireless mobile communication in the millimeter wave frequency band. In the design of microstrip antenna, its radiation efficiency and signal gain are important parameters to measure the performance of microstrip ante...
