Abstract

The invention provides a phased-array antenna unit and a module, which relate to the technical field of phased-array antennas. The phased-array antenna unit comprises a first microwave dielectric substrate, an antenna radiation patch, a second microwave dielectric substrate and a signal transmission layer, wherein the first microwave dielectric substrate, the antenna radiation patch, the second microwave dielectric substrate and the signal transmission layer are connected layer by layer from top to bottom, the signal transmission layer comprises an antenna ground layer, and the signal transmission layer is provided with a cavity; and the antenna radiation patch is provided with a metal signal hole, the signal hole penetrates through the second microwave dielectric substrate and the signaltransmission layer so as to transmit a radio frequency signal through the signal hole and the antenna radiation patch, and the signal hole and the antenna ground layer are arranged at an interval. Thephased-array antenna unit and the module provided by the invention have the advantage of better bandwidth expansion effect.

Description

technical field [0001] The present application relates to the technical field of phased array antennas, in particular, to a phased array antenna unit and a module. Background technique [0002] Microstrip antennas have the advantages of low profile and easy integration, and are widely used in various wireless communications. In order to improve the transmission rate, the antenna is usually required to have broadband characteristics. With the development of technology, the satellite communication system in the ku frequency band begins to use phased array antennas gradually, and some applications require that the bandwidth of the antenna even reach 30%. [0003] However, the bandwidth of the current phased array antenna is generally low. If the bandwidth needs to be expanded, methods such as adding parasitic patches, reducing the relative permittivity of the material, and slot coupling feeding are required. However, these methods are complex in processing and manufacturing. T...
