Welding method of curved-surface microstrip antenna

Abstract

The invention provides a welding method of a curved-surface microstrip antenna, and aims to provide the welding method of the curved-surface microstrip antenna, which is high in welding success rate and high in welding quality so as to meet the reliability requirement of the curved-surface microstrip antenna in long-term use. The method comprises the following steps that a clamping tool for supporting an upper pressing plate and a lower pressing plate through a fixed stand column is prepared, a pressure stand column is sleeved with a main pressure spring, and penetrates through the upper pressing plate to be connected with a main pressure nut; a layer of welding flux is printed at the bottom of the micro-strip in a steel mesh printing mode, and the micro-strip is fixed to a base, a flexible voltage-sharing plate and a rigid voltage-sharing plate through pins; auxiliary pressing plates are arranged at the four corners of the rigid voltage-sharing plate, and the auxiliary pressing plates, auxiliary stand columns and auxiliary pressure springs are fixed to the lower pressing plate through auxiliary pressure nuts to compress main pressure springs and the auxiliary pressure springs, sothat the micro-strip makes close contact with the base; and after assembly is completed, the whole clamping tool is put into a vacuum gas phase furnace to be heated, and after cooling, the tool is disassembled to complete welding of the micro-strip and the base.

Description

technical field [0001] The invention relates to a welding method of a microstrip antenna in the field of electronic equipment. Background technique [0002] With the lightweight of various airborne platforms and missile-borne platforms and the increasing demand for low RCS, the size of the microstrip antenna array increases with the increase of the antenna aperture and the number of array elements, and the shape of the microstrip antenna array The complexity and precision increase with the increase of operating frequency, and the assembly reliability requirements of the antenna array increase with the conformal evolution of the antenna position from inside the cabin to outside the cabin. The curved surface microstrip antenna technology has been conformed to the aircraft at first, and now it is used as a helmet antenna, base station antenna and vehicle antenna, and its tentacles have penetrated into various fields of modern communication. In many practical projects, the carr...
