Problems solved by technology

[0008] Although the above-mentioned antenna can form multi-frequency operation, it has the following disadvantages: the distance between the first conductive sheet A1 and the second conductive sheet B1 is too short, so the bandwidth at low frequency and high frequency is not enough to cover multiple frequencies. A system frequency band; at the same time, the feed-in line and the feed-in point are located close to the first connection part A2, which is a traditional inverted-F antenna structure, and its antenna bandwidth has a certain upper limit, which cannot achieve broadband effect

Embodiment Construction

[0036] Please refer to Fig. 2, it is the first embodiment of the present invention, the integrated multi-frequency antenna with broadband function, it comprises a ground plane 21, a feeding line 22, a first metal radiator 23, a second metal radiator body 24 , a grounded metal radiator 25 and a parasitic metal radiator 26 . The feeding line 22 has a positive signal wire 221 and a negative signal wire 222 , and the negative signal wire 222 is electrically connected to the ground plane 21 . The first metal radiator 23 includes a radiating arm 231 and a feeding metal sheet 232. The radiating arm 231 is located on one side of the ground plane 21 and is horizontally suspended above the ground plane 21, that is, it is not connected to the ground plane. 21, and the radiating arm 231 can also have a side wing 233 in an inverted L shape, and the feed-in metal sheet 232 is arranged perpendicular to the ground plane 21, one end of which is connected to the radiating arm 231, and the other...

Abstract

An integrated multiband antenna with broadband function comprises a grounding surface, a feed-in line, a first metal radiator, a second metal radiator, a grounding metal radiator and a parasitic metal radiator, wherein, the first metal radiator is connected with the positive terminal of a signal of the feed-in line to produce a first high frequency modal. Meanwhile the first metal radiator couples the energy and feeds the energy into the second metal radiator and the parasitic metal radiator and cooperates with the grounding metal radiator to produce respectively a low frequency modal and a second high frequency modal so as to create the broadband effect. The invention uses a multiple antenna integration structure to provide the multiband antenna with enough frequency width so as to meet the system requirements of AMPS(824-894MHz) / GSM(880-960MHz) / GPS(1575MHz) / DCS(1710-1880MHz) / PCS(1850-1990MHz) / UMTS(1920-2170MHz) / Wi-Fi(2400-2500MHz).

Description

technical field [0001] The invention is an integrated multi-frequency antenna, especially a multi-frequency antenna which integrates various antenna structures to form a broadband effect. Background technique [0002] Personal mobile communication has already demonstrated its huge potential and business opportunities in the wireless communication industry. During its evolution, many systems have been developed. The technologies and channels they use are different, and they are also in different regions and markets. However, this phenomenon also causes confusion and inconvenience to system suppliers and consumers. One of the most important points is that different systems use different frequencies, such as GSM 850, DCS 1800 and UMTS. [0003] In order to make the operation more convenient for users, the industry has invested a lot of manpower to develop multi-frequency integrated products. However, the first difficulty to be overcome is the antenna. The antenna can be said to...
