This invention relates to the field of antenna manufacturing tooling technology, and particularly to a welding fixture for an antenna vibrator array assembly, comprising a lower support plate, a support member, an upper cover plate, and a feed plate limiting member. The upper surface of the lower support plate has a positioning area for accommodating and positioning the power divider network board of the antenna array. The support member is fixedly installed on the upper surface of the lower support plate. The upper cover plate is closable and covers the support member. The lower surface of the upper cover plate is provided with a vibrator limiting structure, which is used to respectively accommodate the upper part of each vibrator assembly. The feed plate limiting member is fixedly installed at the bottom of the upper cover plate and extends downward. The upper and lower feed plates of the vibrator assembly are respectively limited and constrained by the upper cover plate body and the feed plate limiting member in a way that is independent and does not interfere with each other, so that the force paths of the upper and lower feed plates are completely independent and do not interfere with each other, thereby avoiding the displacement coupling effect of surface tension on the feed plate when the solder melts.

The application belongs to the technical field of antenna manufacturing, and particularly relates to an antenna pressing die and an antenna pressing die. Through a lower die assembly, including a lower pressing die and an auxiliary fitting assembly; the lower pressing die is provided with a first adsorption site, the auxiliary fitting assembly is arranged on the periphery of the first adsorption site, a pressing groove is arranged in the first adsorption site, and an elastic supporting piece is arranged in the pressing groove; and through an upper die assembly, including an upper pressing die, the upper pressing die is provided with a second adsorption site; so that the first adsorption site and the second adsorption site are arranged in position, when the mold is closed, the ferrite is arranged on the first adsorption site, and the antenna is arranged on the second adsorption site, so that when the antenna is pressed into the pressing groove, the ferrite is partially lifted on the periphery of the antenna and is assisted in fitting by the auxiliary fitting assembly. Thus, efficient fitting of multiple surfaces of the antenna is realized, and the fitting is performed by a low-cost fitting structure without complex mechanical structures.

This invention relates to the field of antenna manufacturing and testing technology, and particularly to a testing device for a remote electronically adjustable unit of a base station antenna. The device includes a base, a remote electronically adjustable unit, and testing components. The remote electronically adjustable unit is fixedly mounted on the base and has at least one output motor, each motor corresponding to a set of testing components. The testing components include two support seats, a lead screw, a nut sleeve, a pull rod, and a gravity load. The two support seats are fixedly mounted on the base and spaced apart along a predetermined direction. The lead screw is rotatably supported between the two support seats and is connected to the power output end of the motor. The nut sleeve is threadedly engaged with the lead screw. One end of the pull rod is fixedly connected to the nut sleeve. The gravity load is connected to the other end of the pull rod. This invention uses a gravity load, utilizing the weight of an object to provide constant resistance, unaffected by the stroke position, overcoming the nonlinearity of spring load force, and providing accurate and repeatable testing results.

The application discloses an EHD printing integrated high-precision FPC antenna and a preparation method, and belongs to the technical field of FPC antennas, and comprises a substrate and a koch snowflake fractal radiation patch formed on the substrate; the metal line of the koch snowflake fractal radiation patch has an optimized nominal width W opt , and W opt is a parameter determined after a collaborative fault-tolerant design of the antenna structure, by modeling the line width manufacturing error of the EHD printing as a random variable within the range of ±15μm and taking the resonance frequency offset of the antenna not greater than 1.5% as an optimization target; the radiation patch is formed after being printed by conductive ink and undergoing synchronous ultraviolet pre-curing and stepwise thermal curing, and the conductive ink contains a load type Ag2O-MXene composite powder; through deep synergy and optimization of the structure fault-tolerant design, special functional materials and precise manufacturing processes, the application solves the mismatch problem in the process from a high-performance design model to high-fidelity physical antenna manufacturing, and especially provides a reliable integrated solution for flexible electronic manufacturing of complex micro-patterns.
