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 ?m to 5.7 ?m and a maximum height (Sz) ranging from 40 ?m to 55 ?m. In addition, a method of manufacturing the antenna module is also disclosed. It includes manufacturing a base frame having a radiator region and forming a radiator in the radiator region, wherein the forming of the radiator includes forming a first conductor layer on an uneven portion of the base frame, forming a second conductor layer on the first conductor layer, and forming a third conductor layer on the second conductor layer.

Abstract: An antenna for a vehicle for enabling to design freely and enhance characteristics of the antenna such as isolation, etc. is disclosed. The antenna includes a substrate and a case configured to cover the substrate. Here, one or more radiator is disposed on an outer surface of the case, and a power is fed to the radiator from the substrate.
