    Abstract: An antenna device includes an antenna space, a barrier, a signal processing device, and a feed space. The antenna space includes first and second antennas that transmit/receive first and second radio frequency (RF) signals in different bands. The barrier includes a penetration region, is disposed adjacent to the antenna space, and reflects the first and second RF signals. The signal processing device adjacent to the barrier, includes first and second RF circuits that process the RF signals. The feed space includes first and second feed layers and is disposed adjacent to and stacked on the signal processing device, and adjacent to the barrier. A first feed line connecting the first RF circuit to the first antenna passes through the first feed layer and the penetration region, and a second feed line connecting the second RF circuit to the second antenna passes through the second feed layer and the penetration region.
