Title:
ANTENNA
Document Type and Number:
Japanese Patent JP2022036886
Kind Code:
A
Abstract:
To provide an antenna which can suppress the gain of side lobes and improve the resolution of detecting targets.SOLUTION: An antenna for suppressing the gain of side lobes includes a substrate, tandem antenna units and a power divider. The tandem antenna units are arranged on the substrate. Each of the tandem units includes a first feed line and radiating elements, and the width of the radiating elements decreases gradually from the middle of the first feed line to the two ends of the first feed line. The power divider is disposed on the substrate and includes a feed port, a second feed line, and transmission lines. The middle of the second feed line is connected to the feed port. The transmission lines are connected to the second feed line respectively, and the output powers of the transmission lines decrease gradually from the middle of the second feed line to the two ends of the second feed line. The transmission lines are respectively connected to the first feed lines. Thereby, the present invention can suppress the gain of the side lobe in a YZ plane and the gain of the side lobe in an XZ plane and improve the resolution of detecting targets.SELECTED DRAWING: Figure 1
