AI Technical Summary

Problems solved by technology

[0004] Since the shark fin module is shaped to be exposed to the outside of the vehicle, there is a high risk of damage due to external impact
Also, smaller shark fin modules require smaller sized antennas
Smaller antennas suffer from degraded radiation capabilities (or broadcast reception)
When several antennas are installed to receive various broadcast signals, the number and / or size of the shark fin modules increases

Abstract

According to certain embodiments, a vehicle includes: a frame including at least one metal panel forming an exterior surface of the vehicle; the antenna is arranged in the vehicle and below the at least one metal panel; a printed circuit board (PCB) module electrically connected to the antenna; and at least one ground extender electrically connecting a ground of the PCB module to the metal panel, where a current flowing in the PCB module flows to the metal panel through the ground extender.

Description

technical field [0001] The present disclosure relates to antennas. More particularly, the present disclosure relates to an antenna device mounted on a vehicle to receive broadcasting, and a method of receiving broadcasting by using the antenna device. Background technique [0002] With the development of communication technology, it has become common to listen to or watch broadcast media such as radio broadcasts or television broadcasts in vehicles. The antenna should be installed on the vehicle to receive broadcasts, and the installation position of the antenna directly affects the performance of the antenna, the stability of the vehicle, and the aesthetics of the vehicle. Currently, most antennas are mounted inside a shark fin module located on the glass or roof of the vehicle. [0003] When the antenna is mounted on the glass of a vehicle, damage to the glass due to external impact can result in damage to the antenna and the need for long cables to connect the antenna t...
