Problems solved by technology

However, it is inevitable that small gaps will appear between the various horizontal layers during assembly. The existence of these gaps will lead to magnetic flux leakage when the signal propagates in the slab waveguide CTS array antenna, and with the increase of frequency, the magnetic flux leakage phenomenon It becomes more serious, it is difficult to be applied to the microwave high frequency band, and the use is limited

Abstract

The invention discloses a processing method of a slab waveguide CTS array antenna. According to the method, the to-be-processed slab waveguide CTS array antenna is divided into N+1 independent layers by taking all stages of waveguide 'E-T' branches as a datum; when processing is conducted, a surrounding edge is arranged at the periphery of the first independent layer to the N-2 independent layer, a surrounding edge is arranged at the periphery of the N+1 independent layer, a clamping groove of which the size matched with that of the surrounding edge of the first independent layer to the N-2 independent layer is formed in the surrounding edge of the N+1 independent layer, and the N-1 independent layer and the N independent layer are installed on the N+1 independent layer through a processing connector; the first independent layer to the N-2 independent layer are sequentially installed; the surrounding edge of the first independent layer to the N-2 independent layer is aligned with the clamping groove formed in the surrounding edge of the N+1 independent layer and clamped into the clamping groove. The processing method has the advantages that the flux leakage phenomenon generated during signal transmission can be reduced, and the method can be applied to processing of the slab waveguide CTS array antenna with the high microwave frequency band.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method of a planar waveguide CTS array antenna. Background technique [0002] The continuous tangential segment (CTS) antenna was first proposed by Raytheon Corporation of the United States in the 1990s. The CTS array antenna is a continuous transverse slit on the planar waveguide and branches are added to the transverse slit to achieve radiation, using TEM mode feed. Compared with other planar array antennas, the CTS array antenna has the following advantages: the continuous tangential segment antenna has relatively high efficiency, which can reach more than 90%; the continuous tangential segment antenna has a relatively low profile, which can be effectively bonded to the carrier platform; The continuous tangential segment antenna has high feeding efficiency and aperture efficiency, and is an extremely important direction for high-gain antennas. At the same time, the CTS arr...
