Printed circuit board including coaxial plated through hole and electronic apparatus including same in wireless communication system

An electronic apparatus A base station comprising:

• a printed circuit board (PCB) including a plurality of layers, the plurality of layers including a first layer to a sixteenth layer;
• an antenna module mounted on a surface of the PCB;
• and
• a radio frequency integrated circuit (RFIC) mounted on another surface of the PCB,
• wherein the PCB includes a coaxial plated through-hole (PTH) electrically connected with the antenna module and the RFIC,
• wherein the coaxial PTH includes a coaxial feedline and a plated region,
• wherein the coaxial feedline is formed through layers starting from a second layer to a fifteenth layer,
• wherein the plated region is formed through layers starting from a third layer to a fourteenth layer and surrounds the coaxial feedline,
• wherein a diameter of the coaxial PTH is 0.7 to 1 mm,
• wherein a diameter of the coaxial feedline is 0.15 to 0.2 mm,
• wherein a fourth to a thirteenth layers are made of a Flame Retardant type-4 (FR-4) material, and
• wherein the first to the third layers and the fourteenth to the sixteenth layers are made of a material having a dissipation factor lower than a dissipation factor of the FR-4 material.
