Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Refer to attached figure 1 , in the present invention, the planar slit array antenna is divided into radiation plate, feeder plate, feeder waveguide and other parts, between the feeder waveguide and the feeder plate, between the feeder plate and the radiation plate are respectively connected by conductive adhesive and screws, Fixing, wherein the radiating plate is formed by processing the metal aluminum plate out of grooves and cracks, and is bonded with the feed plate through conductive glue to form a waveguide cavity. The positioning pins are used for assembling the antenna and installing the printing template, etc.

[0036] Refer to attached figure 2 , the present invention first bonds the feed waveguide and the feed plate together, the bonding process is relatively simple, can use manual glue, the glue layer is coated on...

Abstract

The invention discloses a splicing and processing method of a flat crack array antenna. In the method, the antenna is divided into a radiating plate, a feeding plate, a feeding waveguide and the like; and firstly, the feeding waveguide and the feeding plate are adhered, than an offset print template is installed, and a conductive adhesive is printed on the feeding plate by adopting a template skip printing method so as to adhere the feeding plate and the radiating plate. The method has the advantages of low technical difficulty, low cost, high qualified rate and the like.

Description

technical field [0001] The invention belongs to the technical field of flat panel slot array antenna processing, and in particular relates to a processing method of a flat panel slot array antenna using a bonding process. Background technique [0002] The plate slot array antenna is the main part of the radar, and its function is to transmit and receive radio signals. [0003] The processing methods of flat panel slot array antennas include welding, riveting, bonding, etc. According to foreign reports, welding and riveting are mainly used, but due to technical blockade, it is difficult to know the specific processing methods; domestic welding is mainly used, qualified The rate is generally 67%. [0004] The welding of the plate slot array antenna generally adopts salt bath welding or furnace welding, etc., which requires special equipment such as a welding furnace, and the cost of purchasing equipment is very high. The welding temperature reaches above 600°C, and the param...
