1. An antenna system mounted on a vehicle, the antenna system comprising:
a printed circuit board (PCB) on which an antenna element and electronic components are disposed;
a bottom cover disposed on a bottom of the PCB and configured as a metal plate having a slot region in a region corresponding to a region where the antenna element is disposed; and
a top cover fastened to the bottom cover and configured to accommodate the PCB therein,
wherein the antenna element and the metal plate having the slot region operate as a radiator,
wherein the PCB has a dielectric region, from which a metal pattern is removed such that the antenna element is disposed,
a length of a first metal portion formed at an outer side of the PCB, compared to the antenna element, is shorter than or equal to a length of a second metal part formed at an inner side of the PCB, and
the dielectric region is defined as a region between the first metal portion and the second metal portion.
