The invention relates to a multi-band antenna based on coupled loading. A method coupling an arc-coupled asymmetric coplanar feeding structure and a terminal-loaded coupling radiating unit is used torealize broadband and multi-band design. The multi-band antenna provided by the invention mainly comprises a dielectric substrate 106, the arc-coupled asymmetric coplanar feeding structure, an arc-shaped irregular ground plane 102, an asymmetric coplanar waveguide feed transmission line 101, a first arc-shaped radiating unit 103, a second arc-shaped radiating unit and a third terminal-loaded coupling radiating unit. By adjusting the coupling between the arc-shaped irregular ground plane 102 and the first arc-shaped radiating unit 103 and the dimensions and mutual coupling of the first arc-shaped radiating unit 103, the second arc-shaped radiating unit and the third terminal-loaded coupling radiating unit, the multi-band antenna can meet the wireless communication requirement of multi-bandand single-band indoor base stations. The multi-band antenna provided by the invention has the advantages of convenient integration, simple design, convenient installation and easy debugging, and canbe widely applied to terminals of mobile devices or handheld devices.
Description
technical field [0001] The invention belongs to the field of antenna structures, and in particular relates to a multi-band antenna based on coupling loading. Background technique [0002] Wireless communication technology has entered every aspect of our life. Antenna is the main component of the communication system, and its performance will directly affect the function, performance and communication quality of the wireless communication system. The most representative one is wireless mobile communication technology, especially the current research hotspot, that is, 5G mobile communication technology. As a mobile communication technology, it not only needs to provide better support for the growing wireless communication technology, but also requires backward compatibility with existing mobile communication systems to meet the communication needs of 2G, 3G, 4G and WiFi systems. Therefore, it is necessary to design a multi-band antenna that can not only increase the frequency...
