Antenna module implemented in multi-layered package

An antenna module implemented in a multi-layered package, the antenna module comprising:

• a printed circuit board (PCB) having a plurality of layers;
• a phased array antenna portion arranged on a first outermost surface of the PCB and comprising a plurality of antenna elements, wherein
• the phased array antenna portion has a first region and a second region based on a first axial direction,
• the phased array antenna portion has a third region and a fourth region based on a second axial direction, and
• the first axis and the second axis are orthogonal to each other;
• a radio frequency integrated circuit (RFIC) chip bonded to a second outermost surface of the PCB;
• and
• a plurality of signal connection lines configured to electrically connect the RFIC chip and the phased array antenna portion,
• wherein the plurality of antenna elements comprise a first array antenna and a second array antenna,
• the first array antenna arranged in the first region comprises:
• first patch antennas arranged on the first outermost surface of the PCB, the first patch antennas being arranged spaced apart at a first gap along the second axial direction;
• and
• second patch antennas arranged on one of the plurality of layers inside the PCB,
• portions of the first patch antennas and portions of the second patch antennas are stacked to overlap each other,
• centers of the first patch antennas and centers of the second patch antenna are aligned along a same axis,
• the second array antenna arranged in the second region comprises:
• third patch antennas arranged on the first outermost surface of the PCB, wherein the third patch antennas are arranged spaced apart at the first gap along the second axial direction;
• and
• fourth patch antennas arranged on one of the plurality of layers inside the PCB,
• portions of the third patch antennas and portions of the fourth patch antennas are stacked to overlap each other,
• a first group of the fourth patch antennas are arranged in the third region, and positioned at a second gap along the second axial direction, and
• a second group of the fourth patch antennas are arranged in the fourth region, and positioned at the second gap along the second axial direction.
