An antenna device, a communication device equipped with the antenna device, and a method for manufacturing the antenna device.

摘要

PROBLEM TO BE SOLVED: To improve the utilization efficiency of a substrate in an antenna device capable of radiating a beam in a plurality of directions. An antenna device 1 includes wiring layers 10 and 20 and an antenna layer 30. The wiring layer 20 is divided in the x direction by the slit SL1 extending in the y direction, and the antenna layer 30 is divided in the x direction by the slit SL2 extending in the y direction. The slits SL1 and SL2 overlap in the z direction. The width W1 of the slit SL1 is larger than the width W2 of the slit SL2. The antenna layer 30 includes an antenna conductor P1 formed in the antenna region A1 and an antenna conductor P2 formed in the antenna region A2. As a result, if the wiring layer 10 is bent along the slits SL1 and SL2, the beam can be emitted in a plurality of directions. Moreover, since the width W2 of the slit SL2 is narrow, the utilization efficiency of the antenna layer 30 is improved. [Selection diagram] Fig. 1
