New description: [New technical field] This is a kind of vehicle antenna device and vehicle, especially a vehicle antenna device and vehicle surface that can improve the wireless communication effect. [Prior Art] With the advancement of technology, wireless communication has continued to develop communication protocols and modulation technologies to improve communication distance, transmission rate, and even overcome the rapid movement of the subject, and many wireless communication devices can be used on vehicles. Common wireless communication devices on vehicles include Global (G), Digital TV, Wide Attenuator, and Wireless Feeding. However, these wireless communication devices must rely on the antenna to receive wireless signals, and usually must be placed outside the vehicle or in a position where there is no gold shielding, such as bumper (4), windshield, for better reception quality. However, in order to seek the beauty of the antenna body in the bumper (four), it will be easy to seriously affect the antenna reception due to the shielding of the front and rear vehicles. If the antenna is placed outside the car, the antenna will be shaken due to the engraving, which will affect the reception quality. Therefore, if you want to solve the problem, you can start from the second direction, which is to increase the antenna gain; the other is the effect of the less windy antenna. [New content] Ageing The purpose of this creation is to propose a vehicle antenna device and vehicle that can improve the wireless communication 3 capability, which can improve the above problems. In view of the above object, the present invention proposes a phase antenna device and a vehicle in which the vehicle antenna device is mounted. The antenna device for the vehicle is connected to a wireless communication device', and the antenna device for holding includes: a housing having an accommodating space, the housing at least including a conductive portion, wherein the conductive portion has a broken hole; and the antenna is disposed in the housing The space is maintained at a distance from the conductive portion and electrically insulated to excite the conductive portion to generate at least one resonant mode; and the connecting line is connected to the antenna at one end and to the wireless communication device at the other end for signal transmission. Preferably, the conductive portion is not fed with any electrical signal or ground, and the conductive portion is made of a metal material. Preferably, the projected area of the aperture orthographic projection to the antenna at least partially overlaps the antenna. Preferably, the antenna is selected from the group consisting of a microstrip antenna, a slot antenna, a monopole antenna, a dipole antenna, a panel antenna, a loop antenna, a helical antenna, a coaxial antenna, a crystal antenna, and an array antenna. Preferably, the signal received by the antenna is selected from the group consisting of a satellite signal, a mobile communication signal, a digital television signal, a broadcast signal, and a group thereof. The preferred embodiment of the present invention and its effects are described in conjunction with the drawings. [Embodiment] M406818 A specific embodiment will be described below to explain the contents of the present invention in detail, and the following formula is used as an auxiliary description. The symbols mentioned in the description refer to the schema symbols. 1 i j See Fig. 1 and Fig. 2, which are schematic diagrams of the vehicle and the vehicle antenna device according to the present embodiment. This embodiment proposes a vehicle antenna device 1, which includes a housing 11, an antenna 12, and a connecting line 13. j - | The housing 11 has an accommodating space, and the housing 11 includes at least one conductive portion. The I electric part has a broken hole 1η, and the conductive part does not feed any electric signal or ground. Here, the casing 11 may be composed entirely of a conductive portion or a conductive portion and a non-conductive portion. In essence, the conductive portion may be made of a metal material, that is, the housing u may be entirely made of a conductive metal material. The antenna 12 is disposed in the accommodating space and is electrically insulated from the conductive portion to electrically excite the conductive portion to generate at least one resonant mode. Here, the distance between the antenna 12 and the hole 111 is such that the antenna 12 and the conductive portion produce a capacitance effect. The antenna 12 excites the conductive portion by means of a light-weighted energy to generate a wider frequency band and increase the radiation gain. Since the conductive portion provides a larger area than the antenna 12 to receive or radiate electromagnetic signals, the signal quality can be improved. It should be noted, however, that the projected area of the aperture 111 being projected onto the antenna 12 must at least partially overlap the antenna 12. However, the shape and size of the hole m can be designed according to the requirements of different frequency bands. The antenna 12 can be a group consisting of a microstrip antenna, a slot antenna, a monopole antenna, a dipole antenna, a panel antenna, a loop antenna, a helical antenna 'coaxial antenna, a chip 5 M406818 antenna, and an array antenna. The 13-terminal end of the cable is connected to the antenna 12, and the other end is connected to the wireless communication device 2 for signal transmission. Here, the wireless communication device 21 can be a device having a wireless communication function such as a car computer, a satellite navigation device, an audio system, a digital TV for a car, and the like. That is, the signal received by the antenna 12 can be a group of satellite signals, mobile communication signals, digital television signals, broadcast signals, and the like. Among them, the mobile communication signal includes any conventional mobile communication technology, such as GpRS, GSM, Wimax or other similar technologies. Please refer to the side view of the vehicle antenna device shown in the third embodiment. The housing 11 is entirely composed of the conductive portion 112. However, in order to electrically insulate the antenna 12 from the conductive portion 112, the insulating member n3 may be connected between the housing u and the antenna 12. Here, the insulating member 113 is made of a non-conductive material. Please refer to the figure in Figure 4 for a side view of another vehicle antenna device. The housing 11 includes a conductive portion 112 and a non-conductive portion 114. Preferably, the non-conductive portion of the box-shaped non-conductive portion U4 is formed of a non-conductive material, and the conductive portion 112 is formed of a conductive material, and the conductive portion n and the non-conductive portion 114 are assembled into the casing 11. Although the vehicle antenna device 1 is mounted on the roof of the vehicle as shown in Fig. 1, the present invention is not limited thereto, and any non-metallic shield on the vehicle 2 can be applied, such as a windshield and a bumper. However, the vehicle antenna device j proposed by the present invention transmits the light energy source to Qianxian County, thereby improving the aforementioned defect of 6 M406818 I. Moreover, since the vehicle antenna device 1 has a hard casing li, there will be no
