Title:
TABULAR ARRAY ANTENNA AND WIRELESS MODULE
Document Type and Number:
Japanese Patent JP2019022067
Kind Code:
A
Abstract:
To achieve high gain of an antenna and to properly set the directivity of the antenna.SOLUTION: A tabular array antenna 20 includes a dielectric substrate, a ground conductor layer 37 formed on one surface of the dielectric substrate, a plurality of rows of serial type radiation element rows 41 formed on the other surface of the dielectric substrate, and a parallel feed line formed on the other surface of the dielectric substrate and supplying high frequency power between a feed end point 45s on the other surface of the dielectric substrate and the serial type radiation element row 41. The parallel feed line 45 branches from the feed end point 45s to a radiation element 42 at the end nearest to the feed end point 45s and connects the radiation element 42 and the feed end point 45s. In each of the serial type radiation element row 41, the path length from the feed end point 45s to the radiation element 42 at the end is equal.SELECTED DRAWING: Figure 4
