Abstract

The invention provides a millimeter wave high-gain series-fed microstrip loop antenna. The millimeter wave high-gain series-fed microstrip loop antenna comprises a metal reflecting plate, a dielectric substrate, an antenna radiator and a plurality of coaxial feeder lines; the antenna radiator, the dielectric substrate and the metal reflecting plate are sequentially connected from top to bottom; the coaxial feeder lines are located inside the dielectric substrate, the inner wires of the coaxial feeder lines are connected with the antenna radiator through first feed ports at the top ends of the coaxial feeder lines, and the outer wires of the coaxial feeder lines are connected with the metal reflecting plate at the bottom ends of the coaxial feeder lines. The antenna radiator is a radiation patch, and the radiation patch comprises a plurality of notch annular patch units. According to the invention, the high gain performance of the antenna can be realized through a simple structure. Moreover, the number of the notch annular patch units can be designed according to different needs, and the more the number of the notch annular patch units is, the more obvious the gain effect is.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a millimeter-wave high-gain series-fed microstrip loop antenna, in particular to a millimeter-wave high-gain series-fed microstrip loop antenna based on a ring structure. Background technique [0002] The current wireless communication technology is developing rapidly to meet people's demand for information. With the advent of the 5G era, millimeter-wave frequency bands are gradually being used more and more, and the design of millimeter-wave antennas becomes very necessary. However, since the path loss will also increase in the millimeter wave frequency band, the antenna is required to have a higher gain to reduce the influence of the path loss in propagation. Therefore, it is necessary to design an antenna with high gain characteristics. [0003] Patent document CN213026481U discloses a millimeter-wave antenna unit and an array antenna. The millimeter-wave antenna un...
