一种单端口大频率比双频八木天线
By etching the feed and Yagi-Uda antenna sections on a dielectric substrate, a single-port high-frequency-ratio dual-band Yagi antenna was designed, solving the problem of difficulty in covering microwave and millimeter-wave bands in existing technologies. This resulted in a lightweight and easily integrated dual-band antenna suitable for mobile devices.

AI Technical Summary
Existing dual-band antennas are difficult to cover large frequency bands in both microwave and millimeter-wave bands simultaneously, and antennas with high frequency ratios have high profiles, which limits their application scenarios.
Design a single-port high-frequency-ratio dual-band Yagi antenna. By etching the feeding section, the planar Yagi-Uda antenna section, and the monopole section on both sides of the dielectric substrate, the antenna is excited in the microwave and millimeter-wave bands using different feeding methods. The feeding is achieved using microstrip lines and copper-clad structures. Combined with the planar Yagi-Uda antenna consisting of a driving dipole, a director, and a reflector, dual-band radiation is achieved.
It realizes the excitation of microwave and millimeter-wave band antennas under a single port, which is lightweight, low profile and easy to integrate, suitable for mobile devices, and covers multiple frequency bands of 5G communication.
