New Description: [New Technology Field] This creation relates to an antenna structure, and more particularly to an antenna structure that operates in a variety of wireless communication systems. [Prior Art] Nowadays, an era of information technology and the booming of the electronics industry, with the advancement of various computer-derived high-tech products, mobile communication products and network products, many car dealers will have wireless communication functions. It is listed as a standard equipment for vehicles to increase the competitiveness of the purchase of vehicles. For example: satellite navigation, wireless broadcasting and wireless phone communication. Therefore, vehicle positioning systems such as Global Position System (GPS) antennas, Global System for Mobile Communications (GSM) antennas, and Frequency Modulation Antennas have become automotive manufacturers. Business and car owners # must be purchased for the car. However, the variety of vehicle antennas also complicates the complication of vehicles when installing antennas. If the antennas are installed separately, the time is wasted due to frequent constructions, and the cost of installing multiple antennas is high. If various antennas are installed together, it may cause interference when the antennas of each frequency band operate simultaneously. Therefore, how to propose a vehicle antenna that can integrate and receive the signals of each frequency band, and avoid the problem of mutual interference with the signal M357034 of other frequency bands when receiving or transmitting signals of each frequency band, so as to ensure the reliability of signal transmission and reception of each frequency band is an antenna. The problem that the manufacturer must solve. [New Content] This creative agency aims to provide a kind of antenna structure for a variety of wireless communication systems. According to the above object, the antenna structure of the present invention is provided with a casing, a mobile phone communication antenna, a global positioning system antenna, and a radio broadcast receiving antenna. The housing is composed of a base and a cover body which is defined by a plurality of side walls on the base, and a mobile phone communication antenna is disposed on an inner wall surface of one of the side walls of the cover body, and the global positioning system antenna is disposed at a relatively distant position. A cool corner receiving portion of the base of the side wall is disposed on the inner side wall of the cover inside the casing, and is interposed between the mobile phone communication antenna and the global (four) system antenna. Therefore, the mobile phone communication antenna with similar operating frequency is relatively far away from the global positioning system antenna to avoid mutual interference, and the wireless broadcast receiving antenna whose operating frequency is not similar to the mobile phone communication antenna and the global (four) system antenna is set in (4) telephone. The rail antenna is connected to the whole (four) system. The antenna structure of this creation can stabilize the Lin mobile materials (four) system, the global positioning system and the wireless broadcasting system. [Embodiment] The technical contents, structural features, objectives and effects achieved by the present invention will be described in detail below.

The housing 1 has a substantially rectangular pyramid shape and is provided with a combined base 丨〇 and a cover 11 ′. The cover 11 is provided with a first side wall 12, a second side wall 13 and a third side wall 14 which are connected to each other. The base 1 is formed at an angle 16 opposite and away from the third side wall 14. The mobile telephone communication antenna 2, the global positioning system antenna 3, and the wireless broadcast receiving antenna 4 are all disposed inside the casing 1. In the real implementation, a strong magnet (not shown) can be placed at the bottom of the base 1〇, so that the antenna structure 1 can be firmly attached to the vehicle. When the antenna structure 100 is not used, it can be quickly disassembled. . The mobile telephone communication antenna 2 is disposed inside the third side wall 14 of the cover 11. The mobile telephone communication antenna 2 is provided with a low frequency radiating portion 20 and a high frequency radiating portion 21, and the low frequency radiating portion 20 can transmit and receive a lower frequency mobile telephone communication band such as GSM 850 MHz and EGSM 900 MHz. The high-frequency radiating section 21 can transmit and receive higher-frequency mobile telephone communication bands such as DCS 1800 MHz and PCS 1900 MHz and WCDMA 2100 MHz. The global positioning antenna 3 is disposed at the corner portion 15 because the operating frequency of the global positioning system antenna 3 is about 1575 MHz, which is similar to the higher frequency bands (1800 MHz, 1900 MHz, and 2100 MHz) of the mobile telephone communication antenna 2, in order to avoid the global positioning system. The antenna 3 and the mobile telephone communication antenna 2 interfere with each other. Therefore, a certain distance L must be maintained between the global positioning system antenna 3 and the mobile telephone communication antenna 2. In this embodiment, the distance L between the global positioning system antenna 3 and the third side wall 14 of the cover 11 M357034 is about 89 mm. The radio broadcast receiving antenna 4 is disposed inside the first side wall 12 and the second side wall 13 of the cover 11, and is disposed between the mobile telephone communication antenna 2 and the global positioning system antenna 3.

In the present embodiment, the radio broadcast receiving antenna 4 is in the form of a strip, and the radio broadcast receiving antenna 4 can be a chip antenna. Since the operating frequency range of the radio broadcast receiving antenna 4 is between several hundred KMz and several hundred MHz, which is not similar to the operating band of the mobile telephone communication antenna 2 and the global positioning system antenna 3, the radio broadcast receiving antenna 4 is less likely to be used. The radio broadcast receiving antenna 4 is disposed between the mobile telephone communication antenna 2 and the global positioning system antenna 3, interfering with the mobile telephone communication antenna 2 and the global positioning system antenna 3. Please refer to the third figure, which is an antenna performance test chart of the mobile phone communication antenna 2. In this embodiment, the mobile phone communication antenna 2 can operate in the bands of GSM 850 MHz, EGSM 900 MHz, DCS 1800 MHz, PCS 1900 MHz and WCDMA 2100 MHz. When the mobile telephone communication antenna 2 operates in the GSM 850 MHz band, the efficiency is approximately 66.15 percent. When the mobile telephone antenna 2 operates in the GSM 900 MHz band, the efficiency is approximately 66.18. When the mobile telephone communication antenna 2 operates in the DCS 1800 MHz band, the efficiency is approximately 66.87 percent. When the mobile telephone communication antenna 2 operates in the PCS 1900 MHz band, the efficiency is about 67.16. When the mobile phone communication antenna 2 operates M357034 in the WCDMA 2100MHz band, the efficiency is about 62.95%. Referring to the fourth and fifth figures, the fourth figure is the electric field gain diagram of the global positioning system antenna 3. From the fourth figure, the electric field gain of the global positioning system antenna 3 is better than the horizontal polarization and the vertical polarization. Component. The fifth figure is the magnetic field gain map of the global positioning system antenna 3.

In order to avoid interference between the mobile telephone communication antenna 2 and the global fixed (four) system antenna 3, the operation frequency is different from that of the mobile telephone communication antenna 2 and the global positioning system antenna 3, and the wireless broadcast receiving antenna 4 is disposed in the mobile phone communication. The antenna 2 is connected to the global antenna 3. Therefore, the antenna structure 1 can be stably operated in a mobile phone communication system, a global (four) system, and a wireless broadcasting system.
