Problems solved by technology

[0005] Although some dielectric materials have high ε r value, but its μ r When it is 1, it is impossible for the antenna to obtain good impedance matching performance and wide bandwidth when used on the antenna substrate
[0006] For metal magnetic materials, although their saturation magnetization is high and the ferromagnetic resonance frequency is high, due to the existence of eddy currents, the loss is high, and it is difficult to work under the condition of Sub 6GHz
For soft ferrite materials, such as nickel-zinc ferrite, manganese-zinc ferrite, etc., due to the limitation of Snoek limit, the application frequency is difficult to break through GHz

Description

Technical field [0001] The present invention relates to an electronic material technology, and more particularly to an antenna substrate material. Background technique [0002] Massive MIMOs have not reversed the core technologies of 5G mobile communication systems. Based on the limited time and frequency resources, Massive MIMO technology uses hundreds of antenna units at the same time, and has significantly improved the efficiency of data throughput and energy. [0003] However, coupling between the antennas is a technical problem. Especially in the mobile terminal, the number antenna is concentrated in limited space, and the coupling problem is also more severe. [0004] To this end, it has high μ r High ε r The magnetic material is used as the substrate of the antenna, which reduces the geometric size of the antenna, the size of the size and the shrink factor N = (μ) r ε r 1 / 2 positive correlation. [0005] Certain dielectric materials have high ε r Value, but it is μ r For a...
