The invention discloses a single-port feeding dual-frequency antenna, comprising a dielectric substrate, a radiation patch, a grounding metal layer, a low-pass filter structure, a microstrip line anda feed port, wherein the radiation patch and the grounding metal layer are disposed on the first surface and the second surface, away from each other, of the dielectric substrate respectively; at least one radiation slit is formed in the grounding metal layer; the low-pass filter structure is located on the first surface and is connected to the radiation patch; the low-pass filter structure is located in an area between the projection of the radiation patch and the projection of the radiation slit on the first surface; and the microstrip line connects the feed port to the low-pass filter structure. The invention also discloses an electronic device. The invention provides the single-port feeding dual-frequency antenna and the electronic device. The single-port feeding dual-frequency antennasimultaneously feeds a monopole and a slit through a single feed port via the microstrip line, and the whole antenna can simultaneously work in microwave and millimeter wave frequency bands. The low-pass filter structure is introduced between the microstrip line and the monopole to provide a high-isolation dual-frequency antenna.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-frequency antenna fed by a single port and an electronic device. Background technique [0002] With the development of wireless communication technology, the spectrum of the microwave frequency band is widely used in various communication fields, resulting in problems such as crowded frequency bands and narrow available frequency bands, while the millimeter wave band has attracted widespread attention due to its high frequency band and wide bandwidth. , so the millimeter-wave antenna enters the field of antenna research and has become a research hotspot in recent years. [0003] Compared with the currently widely used microwave communication, millimeter wave communication has a high transmission rate, but its short transmission distance also limits its application. Therefore, dual-frequency antennas that can work in both microwave and millimeter wave bands have higher Va...
