A Fuze Detector Microstrip Flat Panel Antenna

Abstract

The invention discloses a fuze detector microstrip flat panel antenna, which belongs to the field of antennas and includes a microstrip array antenna, a first dielectric substrate, a second dielectric substrate, a first metal layer, a second metal layer, a feed network, and a waveguide layer , the first microstrip line-waveguide transition, the second microstrip line-waveguide transition. The microstrip array antenna includes N antennas distributed at equal intervals and parallel to each other, each antenna includes M antenna elements, and the M antenna elements are distributed alternately left and right with respect to the feeder line, and are connected with the feeder line to form a comb. The antenna of the present invention realizes the different-plane structure of the antenna and the active device, reduces the loss and interference of the feeder line, reduces the influence of the active network on the antenna, and can effectively suppress the side lobe through the metal patch, and has the advantages of small size, low cost Low, high gain, low sidelobe, high isolation, etc., can meet the requirements of short-distance millimeter-wave fuze detectors.

Description

technical field [0001] The invention belongs to the field of antennas, in particular to a fuze detector microstrip planar antenna. Background technique [0002] The fuze is a control device that uses target information and environmental information to detonate or ignite the warhead charge under preset conditions. Fuzes are mainly used in military weapon systems. Modern warfare models focus on precise strikes and efficient damage to targets. Therefore, precision strike ammunition and anti-aircraft and anti-aircraft ammunition including key components fuzes have a growing stage of development. According to the different methods of obtaining target information, fuzes are divided into three categories: trigger fuzes, proximity fuzes and execution fuzes. The trigger fuze works by direct contact or collision with the target entity: the proximity fuze senses the characteristics of the target through some non-direct contact methods, and it will work when the conditions are met; the...

Problems solved by technology

At present, there is a lack of research on 77GHz millimeter-wave antennas for fuzes, and there are very few designs for 77GHz millimeter-wave antennas. The size of the actual application is not considered. The designed antenna is too large, the feed loss is too large, and the antenna’s transceiver isolation. Not advanced question
