Embodiment Construction

[0022] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0023] see figure 1 , The bow-tie antenna of the present invention is composed of an antenna arm 1 on the upper surface and an antenna arm 2 on the lower surface. The antenna arm 1 on the upper surface and the antenna arm 2 on the lower surface form a certain overlap. Among them, the antenna arm on the upper surface is fed by the coaxial interface 4 through the feeding unit 3, the antenna arm 2 on the lower surface is connected to the outer conductor of the coaxial interface 4, and the inner conductor 11 of the coaxial interface 4 is fed by a probe , connected to the feed unit 3.

[0024] see figure 2 , as shown in Figures (a) and (b), the upper surface antenna arm 1 and the lower surface antenna arm 2 of the antenna are printed on the upper and lower surfaces of the dielectric substrate 5 respectively. The length of the antenna arm 1 on the u...

Abstract

The invention discloses a dual-band tie-shaped antenna oriented to multi-system mobile communication applications. The dual-band tie-shaped antenna comprises a dielectric substrate as well as an upper-surface antenna arm and a lower-surface antenna arm which are printed on the upper surface and lower surface of the dielectric substrate; the upper-surface antenna arm and the lower-surface antenna arm are in mutual asymmetric overlap so as to form a tie shape; the tail end, at the overlap, of the lower-surface antenna arm is provided with a groove; the upper-surface antenna arm is connected with a feed unit; a coaxial interface is arranged in the feed unit; and the upper-surface antenna arm is connected with the lower-surface antenna arm through the coaxial interface. According to the dual-band tie-shaped antenna oriented to the multi-system mobile communication applications, the working band of the antenna can be effectively controlled, so that the dual-band tie-shaped antenna can cover the low bands of a 2G (2nd Generation mobile communication system), a 3G (3rd Generation mobile communication system) and a WLAN (Wireless Local Area Network) and can also serve as a unit antenna of mobile communication base stations or repeaters for the 2G, the 3G and the WLAN.

Description

technical field [0001] The present invention relates to a dual-band antenna for mobile communication applications of various systems, in particular to a dual-band broadband antenna that can work in 2G frequency band, 3G frequency band and WLAN low frequency band, has a simple structure and is convenient for production and assembly, and can also be used as The unit structure of the base station or repeater antenna array of the wireless communication system. Background technique [0002] Mobile communications and the Internet are the two fastest-growing, largest market potential and most attractive prospects in the world's telecommunications industry today. With the opening of the third-generation mobile communication system (3G, including WCDMA, TD-SCDMA and CDMA 2000 systems), the second-generation mobile communication system (2G, including GSM) will appear in my country's mobile communication market for a long time to come. , CDMA system), third-generation mobile communicat...
