        Abstract: In this paper, a 5G communication multi-band miniaturized quasi-omnidirectional antenna based on electric-LC (ELC) structure loading is proposed. Multi-band is realized by using branch patches. The defective ground structure (DGS) and comb-shaped slots structure are used to optimize the impedance matching. The meandered strip structure and ELC structure is loaded to achieve good omnidirectional radiation. The antenna S parameters, gain and pattern are tested. The measured results show that the |S11|≤−10 dB impedance bandwidth is 0.82−0.94 GHz, 1.76−3.63 GHz and 4.80−4.90 GHz, respectively, covering mobile communication 2G, 3G, 4G, 5G and other frequency bands. The antenna proposed in this paper has the advantages of small size, wide bandwidths, quasi-omnidirectional radiation, etc., and is suitable for wireless communication terminal equipment.
