AI Technical Summary

Problems solved by technology

[0003] The current miniaturization technologies include meandering technology, short-circuit loading, lumped parameter loading, and increasing the dielectric constant and magnetic permeability of the substrate, etc., but the miniaturization of the antenna will affect the bandwidth of the antenna. Generally, the bandwidth will be narrowed. The resonance characteristics become worse, so the bandwidth problem needs to be considered

In addition, technologies such as meandering current and short-circuit loading are based on microstrip antenna technology, whose radiation has strong directivity, and it is difficult to realize omnidirectional antenna
