Abstract
An antenna module includes a base frame and a conductive pattern disposed on the base frame, wherein the conductive pattern includes a first conductor layer disposed on the base frame, a second conductor layer disposed on the first conductor layer, and a third conductor layer disposed on the second conductor layer. A surface of the conductive pattern has an areal roughness expressed by an arithmetical mean height (Sa) ranging from 4.7 μm to 5.7 μm and a maximum height (Sz) ranging from 40 μm to 55 μm.
