Description

Vehicle and antenna {VEHICLE AND ANTENA}

The present invention relates to a vehicle and an antenna, and to an antenna mounted for a vehicle and provided to receive radio waves, and to a vehicle having the same.

A typical vehicle antenna is a glass antenna that is installed on the rear window of a vehicle to receive AM/FM radio broadcast signals. Recently, in addition to radio broadcast signals, antennas for receiving signals such as DMB, GPS, and telematics have been added. For this, a shark pin antenna or a pole type antenna is installed on the outer surface of the roof panel of the vehicle.

However, the shark pin antenna or pole type antenna installed on the outer surface of the roof panel of the vehicle is exposed to the outside of the vehicle, thus limiting the design of the vehicle. In addition, since the shark pin antenna must match the color of the vehicle, the manufacturer of the shark pin antenna has a burden to prepare various color products in consideration of the color of the vehicle.

The body 302 has a substantially hexahedral box shape.

A pair of coupling portions (metal insert nuts or metal connectors) 304 for mechanically coupling the helical coil poles are provided on both sides of the main body 302. Although only one coupling part 304 is shown in FIG. 3, the same coupling part 304 is provided on the opposite side of the main body 302 which is not visible in FIG. 3.

The circuit provided inside the main body 302 includes an amplifier 602 for amplifying the received signal. In the hidden antenna 102 according to the embodiment of the present invention, the amplifier 602 is preferably installed at a position closest to the helical coil pole 402. This is to configure the path until the RF signal received by the helical coil pole 402 is transmitted to the amplifier 602 as the shortest path. As the distance between the helical coil pole 402 and the amplifier 602 increases, a greater loss occurs in the signal transmission process. Therefore, in the hidden antenna 102 according to the embodiment of the present invention, the helical coil pole 402 and the amplifier It is intended to reduce signal loss by minimizing the distance between (602).

Accordingly, the structure shown in Fig. 7A remains room for improvement in terms of cost reduction.

7B is a diagram showing a case where the amplifier 714 is present in the main body 702, but the signal path from the antenna to the amplifier 714 is long because the distance between the amplifier 714 and the antenna is long. In this case, since the signal received from the antenna must go through a very long path to reach the amplifier 702, the loss of the signal in this process is inevitable. The structure shown in Fig. 7B remains room for improvement in terms of stable signal transmission.

The cross section of the support part 850 is circular and thus forms a cylindrical shape as a whole. At one end of the support part 850, a fastening part (for example, an insert bolt) 852 for mechanically coupling to the coupling part 304 of the main body 302 is formed. The outer diameter of the fastening part 852 is the same as the inner diameter of the fastening part 304, and the outer diameter of the fastening part 852 is formed with a thread, so that the fastening part 852 and the coupling part are rotated through the rotation of the helical coil pole 402. 304 can be mechanically coupled. That is, the body 302 and the helical coil pole 402 may be mechanically coupled by the coupling portion 304 in the form of an insert nut and the coupling portion 852 in the form of an insert bolt.

In addition, a pole cap 872 is mounted on the other end of the support 850 in a state in which the helical coil 860 is wound and the cover 870 is mounted. The cover 870 and the pole cap 872 are intended to prevent damage such as corrosion by preventing exposure of the helical coil 860.
