Slotted Waveguide Antenna

Introduction

With the improvement of radar anti-jamming requirements and the development of pulsed Doppler radar, rectangular slotted waveguide antenna has been widely used in these microwave communication and radar systems that require narrow beams or given beams. In particular, it has the characteristics of small size, light weight, high aperture efficiency, low wide-angle side lobes, etc., and is the preferred form in airborne radar. The slits on the waveguide form different forms of slits according to their cutting positions.

Classification

Commonly used slits include inclined slits on the narrow side of the waveguide, longitudinal slits on the broad side of the waveguide, transverse slits, and slits on the centerline of the broad side of the waveguide to the oblique slits. They can be resonant or non-resonant. Since these slits cut the surface current, they will radiate energy to the external space, and the number, location, size, and arrangement of these slits can be carefully selected to generate various practical antenna patterns.

Characteristics

The slotted waveguide antenna has the characteristics of easy control of oral field distribution, high antenna aperture efficiency, stable performance, simple and compact structure, high strength, convenient installation, etc., and it is easy to achieve narrow beam, low sidelobe, and even ultra-low sidelobe.

Advantage

Compared with the traditional antenna, the waveguide slot antenna has many advantages, its aperture distribution is easy to control, there is no energy loss caused by feed illumination, and the observation range will not be affected by aperture occlusion.

Application

The slotted waveguide antenna is widely used in microwave communication and radar systems. It has the advantages of high efficiency, high power resistance, and convenient integration of the feeding system and the radiation system. Its basic radiation principle is to cut the surface of the waveguide by slitting the surface waveguide. The equivalent radiation unit is formed by the current, and the equivalent radiation unit can have different amplitudes and phases according to the position of the cutting, the angle of the slot, and the width and length of the equivalent radiation unit. By designing the amplitude and phase of the radiation unit, a waveguide can be formed. Slit Antenna Array.
