Slot type enhanced coupling antenna

Abstract

The invention discloses a slot type enhanced coupling antenna. The slot type enhanced coupling antenna comprises a substrate, a plurality of radiation slots which produce resonant frequency, control positive signal components and are located on the substrate in parallel and a plurality of radiation slots which produce resonant frequency, control negative signal components and are located on the substrate in parallel; specific distances exist between the radiation slots of the positive signal components; specific distances also exist between the radiation slots of the negative signal components; coupling regions of the radiation slots are formed between the adjacent radiation slots; the radiation slots of the positive signal components and the radiation slots of the negative signal components can be arranged in a linear mode or a V-shaped mode; the radiation slots of the positive signal components and the radiation slots of the negative signal components are mutually connected at one end of a signal source through impedance matching and electromagnetic induction. The slot type enhanced coupling antenna can receive and control radio signals within very wide frequency, and therefore the coverage of the radio signals is enlarged at a low cost.

Description

Technical field [0001] The invention relates to a slot type antenna, in particular to a slot type enhanced coupling antenna. Background technique [0002] Blind areas in current wireless transmission systems, such as weak GSM / PCS / 3G / 4G signal areas, usually occur in high-rise buildings or buildings with very complicated internal structures. Therefore, it is necessary to solve this problem. At present, in order to improve the signal propagation effect, we increase the number of relays and micro base stations. [0003] The use of relay technology to improve the signal propagation effect is to use two antennas and an active relay in a two-way amplifier circuit or a passive relay that connects two antennas through a coaxial cable or waveguide. The specific implementation method is to install an antenna outside the building with good propagation effect, and then connect the antenna in the weak signal area in the building through a waveguide or coaxial cable, so as to improve the signa...

AI Technical Summary

Problems solved by technology

[0005] However, no matter whether relay or miniature base station technology is used to solve the problem of signal blind area, it needs high cost and needs to update the wireless communication frequency extension equipment

In addition, wireless signals transmitted externally and wireless signals transmitted internally overlap in buildings with adjacent windows, and terminals connected to corresponding wireless communication systems may also cause multipath fading due to the overlapping of the above signals
