Embodiment 1

[0018] like figure 1 , 2 As shown, a ridge waveguide series feeding network includes a plurality of ridge waveguides and a rectangular waveguide power divider. There is a common wall between each ridge waveguide and the rectangular waveguide, and the common wall is provided for connecting the ridge waveguide and the The slot of the rectangular waveguide. The invention greatly compresses the size of the rectangular waveguide feeding structure.

[0019] preferred, such as figure 2 As shown, the slot is roughly S-shaped, specifically including a straight slot part in the middle and curved parts at both ends; wherein the straight slot part is arranged obliquely relative to the length direction of the ridge waveguide and the rectangular waveguide. By adjusting the angle between the straight slit part of the S-shaped slot and the axis of the rectangular waveguide, the feed power of the branch ridge waveguide can be adjusted, and the adjustment of the length of the curved part of...

Embodiment 2

[0025] In this embodiment, the ridge waveguide series feeding network is applied to the feeding network of the antenna array. Each ridge waveguide is respectively connected with an antenna line source; feeding through the feed network can greatly shorten the lateral space of the radiation slot waveguide, and simplify the feed network structure inside the antenna.

Abstract

The present invention belongs to the microwave technology field, in particular to a series feed network from a rectangular waveguide to a ridge waveguide. The series feed network comprises a plurality of ridge waveguide tubes and a rectangular waveguide power divider, and a common wall is formed between the ridge waveguides and the rectangular waveguide power divider and is equipped with an S-shaped gap used for communicating the ridge waveguides and the rectangular waveguide power divider. According to the present invention, by an electromagnetic coupling mode of the S-shaped gap, a feed problem of the rectangular waveguide power divider to the series ridge waveguides is solved.

Description

technical field [0001] The invention belongs to the field of microwave technology, and in particular relates to a ridge waveguide series feeding network. Background technique [0002] With the diversification of functional requirements for electronic systems such as radar and communication, the demand for antennas is developing in the direction of multi-polarization. Dual-polarization antennas can provide electronic systems with rich target recognition performance and strong anti-interference ability. It is widely used to meet the multi-functional requirements of electronic systems. At present, there are many forms of dual-polarized antenna designs at home and abroad. The slotted waveguide dual-polarized antenna is an antenna suitable for working in the high-frequency band. Its advantages are low loss and high reliability. It can be used on land, sea, air, days and other environments. [0003] One of the difficulties in the implementation of the slotted waveguide dual-pola...
