Classification: CPC H | IPC H

Claim 9:
10. An electronic apparatus comprising:
a printed circuit board (PCB) including a plurality of layers;
an antenna module including an antenna substrate and a plurality of antennas, the antenna module disposed on a side of the PCB; and
a radio frequency integrated circuit (RFIC) module including a package and an RFIC, the RFIC module being mounted on another side opposite to the side of the PCB,
wherein the PCB includes a coaxial plated through-hole (PTH) electrically connected 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 a first set of layers of the plurality of layers,
wherein the plated region is formed to surround the coaxial feedline through a second set of layers and the first set of layers includes the second set of layers,
wherein the plurality of layers is divided into a plurality of stages including a first stage, a second stage, and a third stage,
wherein a dissipation factor of a material in the first stage and in the third stage is lower than a dissipation factor of a material in the second stage between the first stage and the third stage, and
wherein the second set of layers includes layers of the second stage between the first stage and the third stage.
