A 5G Dual Polarized High Gain Directional Antenna with Miniaturization

The continuous development of modern mobile communication, radar and electronic countermeasure system has driven communication equipment towards miniaturization and multi-functionalization, so the communication system has higher requirements on the operating bandwidth characteristics, radiation characteristics, and volume size of antenna and array antenna. A 5G dual-polarized high gain small directional radiating Sub-6GHz antenna is proposed. The designed antenna consists of a coplanar waveguide feed, a dual element butterfly radiating patch, and a parasitic rectangular strip around the patch. The parasitic strip is used to increase the bandwidth of the antenna and also used to improve the directional characteristics of the antenna. It is verified by HFSS simulation that the antenna has a directional antenna with wide bandwidth and good directional radiation pattern, which is suitable for micro-deformation monitoring radar applications.
