Microstrip line filtering radiation oscillator, filtering radiation unit and antenna

Abstract

The invention relates to a microstrip line filtering radiation oscillator, a filtering radiation unit and an antenna. The microstrip line filtering radiation oscillator includes a substrate; a plurality of first metal sheets which are parallel to one another and are arranged at intervals are arranged on the front surface of the substrate; and a plurality of parallel second metal sheets arranged atintervals are arranged on the back face of the substrate, and the first metal sheets and the second metal sheets are correspondingly staggered and are coupled through coupling parts arranged on the substrate in a penetrating mode. The microstrip line filtering radiation oscillator has the functions of signal radiation and interference suppression at the same time. A filtering radiation unit comprises at least one oscillator and can be matched with a high-frequency radiation element in use to achieve the purpose of simultaneously radiating a high-frequency signal and a low-frequency signal. the antenna provided by the invention comprises at least one filtering radiation unit, and can transmit a low-frequency signal and a high-frequency signal at the same time, thereby effectively improvingthe integration degree of the antenna, and reducing the size of the antenna.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a microstrip filter radiation oscillator, a filter radiation unit and an antenna. Background technique [0002] With the rapid development of communication, the fifth generation of communication has come. Due to the consideration of operating costs, the 4G+5G model will become the mainstream trend of communication development. However, when 4G antennas and 5G massivemimo antennas are mixed in an array, the unit radiation unit of the 4G antenna will cause serious interference to the radiation unit of the 5G antenna, which will cause the beam deformation of the massivemimo antenna to affect the coverage and the isolation between systems is not up to standard. [0003] In order to solve the above problems, the technical solution commonly used in the prior art is to insert a band-stop filter on the arm of the low-frequency radiation unit, thereby effectively suppressing the induced current ge...
