Abstract
The invention discloses a dual-polarized millimeter-wave dielectric resonator antenna for a mobile terminal, belonging to the technical field of wireless communication and antennas. The substrate-integrated cylindrical dielectric resonator antenna includes an upper layer metal, an upper dielectric substrate, an intermediate layer metal and a lower dielectric substrate, all of which are rectangular and sequentially bonded. Metal columns and air columns are arranged on the upper dielectric substrate, and the intermediate layer metal A rectangular opening a and a rectangular opening b are opened on the top, and the lower surface of the lower dielectric substrate is covered with a microstrip feeder a and a microstrip feeder b; the radio frequency signal is respectively input from the starting ends of the microstrip feeder a and the microstrip feeder b, and passes through the rectangular opening a and The rectangular opening b is coupled into the cylindrical dielectric resonator, and finally radiates into free space through dielectric resonance. The present invention overcomes the problem of single polarization of the existing millimeter wave antenna, the impedance bandwidth of the antenna is large, and the sensitivity to peripheral devices such as mobile phone glass and casing is low, and the present invention is easy to process and has high integration with mobile phone terminals.
Description
technical field [0001] The invention belongs to the field of wireless communication and antenna technology, and in particular relates to a dual-polarized millimeter-wave dielectric resonator antenna for a mobile terminal. Background technique [0002] The rapid development of the new generation of mobile communication technology (5G) has put forward more and more stringent requirements for wireless communication equipment. Antenna is one of its key parts, and its performance directly determines the communication quality and user experience. In order to improve the information transmission rate, the operating frequency band of the antenna is raised to the millimeter wave frequency band, and the antenna is often required to have a wider bandwidth and a higher gain. As the frequency increases, the metal loss has a more significant impact on the antenna efficiency and affects the gain of the antenna. At the same time, the space provided by the mobile phone terminal for the mill...
