    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.

    Abstract: A radio frequency (RF) apparatus includes a radio frequency integrated circuit (RFIC) chip and an antenna module disposed on an upper surface of the RFIC chip. The antenna module includes a first antenna patch that is in parallel with the RFIC chip, the first antenna patch including a first penetration point, and a first power feed point connected to a first power feed line to transmit and receive a first RF signal of a first frequency band; and a second antenna patch disposed above the first antenna patch in parallel with the first antenna patch, the second antenna patch including a second power feed point connected to a second power feed line that penetrates through the first penetration point to transmit and receive a second RF signal of a second frequency band. The first penetration point is formed in a first region of the first antenna patch in which influence on an electric field generated by the first antenna patch via the first power feed point is minimized.
