The invention discloses a dual-frequency common-caliber waveguide slot waveguide antenna and a design method thereof, and an antenna array. The dual-frequency common-caliber waveguide slot waveguide antenna comprises a radiation port, a radiation sidewall, a first waveguide cavity, a second waveguide cavity, a Ku-band input port and a Ka-band input port; the radiation port, the radiation sidewall,the first waveguide cavity, the second waveguide cavity and the Ka-band input port are sequentially disposed from top to bottom, and the Ku-band input port is disposed on the first waveguide cavity.The dual-frequency common-caliber waveguide slot waveguide antenna and a design method thereof, and the antenna array are high in efficiency, high in gain, easy to process, dual-band and large in distance.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-frequency common-aperture waveguide slot waveguide antenna, an antenna array and a design method. Background technique [0002] An antenna (antenna) is a transformer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenn...
