Abstract

An embodiment of the present invention provides a multiband common-caliber antenna. The multiband common-caliber antenna of the present invention comprises a continuous transverse stub (CTS) antenna and a microstrip patch antenna. The CTS antenna comprises a planar waveguide feeding structure and multiple strip-shaped waveguide radiation units disposed on the planar waveguide feeding structure and disposed in a spaced manner along a first direction. A medium substrate is disposed between every two strip-shaped waveguide radiation units and on the upper surface of the planar waveguide feeding structure. Microstrip patch antenna arrays are disposed on the upper surface of the medium substrate. Each of the microstrip patch antenna arrays comprises multiple microstrip patch antenna units disposed in a spaced manner along a second direction perpendicular to the first direction. The number of the microstrip patch antenna arrays disposed on at least one of the medium substrate is not less than 2. The microstrip patch antenna arrays disposed on the medium substrates form the microstrip patch antenna. The embodiment of the present invention suppresses mutual coupling between surface waves of the microstrip patch antenna and the antenna.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a multi-band common-aperture antenna. Background technique [0002] With the rapid development of wireless communication, a communication system is required to have multiple functions, so a matching dual-band or multi-band radiation and receiving system is required. However, in many communication devices, due to the requirements of device integration and miniaturization, there is not enough space allocated to two or more antennas of different bands. In order to realize the integrated design of antennas of different bands in a limited space, it is necessary to design the antennas of different bands on the same aperture to realize the sharing of apertures. Common-aperture dual-frequency or multi-frequency antennas are also required to reduce equipment costs, improve equipment integration, and promote intelligent antenna integration. [0003] figure 1 It is ...
