Title:
ANTENNA DEVICE AND COMMUNICATION APPARATUS EQUIPPED WITH THE SAME, AND ANTENNA DEVICE MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2022048020
Kind Code:
A
Abstract:
To increase the utilization efficiency of a base plate in an antenna device that can radiate beams in a plurality of directions.SOLUTION: An antenna device 1 has wiring layers 10 and 20 and an antenna layer 30. The antenna layer 20 is divided in an x direction by a slit SL1 extending in a y direction, and the antenna layer 30 is divided in the x direction by a slit SL2 extending in the y direction. The slits SL1 and SL2 overlap in a z direction. Width W1 of the slit SL1 is larger than width W2 of the slit SL2. The antenna layer 30 includes an antenna conductor P1 formed in an antenna area A1 and an antenna conductor P2 formed in an antenna area A2. As a result, when the wiring layer 10 is bent along the slits SL1 and SL2, beams can be radiated in a plurality of directions. Moreover, since the width W2 of the slit SL2 is narrow, utilization efficiency of the antenna layer 30 is increased.SELECTED DRAWING: Figure 1
