Considering the conditions of any mobile use of the car, except for ETC and other devices used in specific places, the general vehicle antenna should be an omnidirectional antenna. At present, the improvement of radio and TV receivers is being actively promoted, and some models use two antennas for radio reception, and 3 to 4 antennas for TV reception. For the use environment, the antenna must have excellent water resistance, vibration resistance, corrosion resistance, etc., while also taking into account safety, wind noise, and the impact on the shape of the vehicle. The uniaxial antenna that forms the basis of the vehicle antenna should have a length of 1/4 of the wavelength of the received radio wave, but the length of the antenna that can be installed on the car is only about 1m. Multiple antennas should be installed in limited locations while taking into consideration the securing of antenna reception performance, prevention of interference between antennas, feasibility of installation, and commerciality of appearance.
