Multi-antenna module

Abstract

The invention provides a multi-antenna module, which comprises an earthing surface, a main conductor, a minor conductor and a plurality of coupled conductors. A main structure with a main radiation arm and a minor radiation arm parallel to each other is utilized to infinitely extend a plurality of antenna conductor units in the same antenna structure, and through capacitance-coupling effect between the parallel radiation arms and the own inductance effect of the radiation arms, interfering signals among antennae are effectively reduced so as to achieve multi-antenna system integration and demand for size miniaturization. In addition, as the earthing surface, the main conductor, a minor conductor and the coupled conductors are all connected with the same earthing surface, the difficulty inconfiguring antenna space and assembling is lowered so as to ensure that the module can be easily accommodated in various electronic devices.

Description

technical field [0001] The invention relates to a multi-antenna module, in particular to a multi-antenna module with infinitely extending antenna units in the same main body structure. Background technique [0002] The vigorous development of wireless communication technology has led to the full development of antenna technology, especially in the market for the miniaturization of antenna design and the communication requirements of transmission systems covering multiple system frequency bands, so a variety of composite antennas (Combo antenna) have been proposed successively The design integrates different types of antennas used in different wireless communication systems or different frequency bands into a single antenna structure, so as to shorten the antenna configuration size and meet the requirements of multiple operating frequency bands. [0003] Such as figure 1 As shown, it is a schematic plan view of a mobile phone antenna integration device for a multi-mode wirel...

Problems solved by technology

[0005] However, in order to reduce the radiation interference effect between the antennas, the planar inverted F antenna 101 must be arranged on the first side of the base 104, the monopole antenna 102 is placed on the side of the base 104, and the flat panel antenna 103 is placed on the first side of the base 104 The position away from the monopole antenna 102, because the antenna is located on different planes of the base 104, in order to make the antenna have enough space for the radiation conduction surface, this configuration form will increase the difficulty of antenna installation, making it difficult to integrate in various electronic products. In addition, the isolation spacing of the antennas must be separated by 6mm and 2mm respectively, which greatly increases the antenna configuration space, resulting in that the radiation efficiency of the integrated antennas cannot be greatly improved. In addition, the isolation efficiency of different antennas is also easily limited, and usually cannot be completely Achieve the effect claimed by the design
