ANTENNA DEVICE

摘要

Disclosed is an antenna device. An antenna device according to one embodiment of the present invention is a device for transmitting and receiving signals having multi-frequency bandwidths, and comprises: a first antenna electrically connected to a first substrate; a second substrate formed separated at a predetermined height from the first substrate by a plurality of pillars formed apart from one another on top of the first substrate; and a second antenna formed on the second substrate and electrically connected to the second substrate to transmit and receive signals having multi-frequency bandwidths. Here, one pillar of the plurality of pillars is made of a conductor to electrically connect the first substrate with the second substrate.
