Abstract

The invention provides a Ka-band tilt-structure active phased array antenna, so as to provide an active phased array antenna which is high in integration density and can improve maintainability and interchangeability. According to the technical scheme, one path of RF signals transmitted by a transmitting signal processing terminal are transmitted to a power distribution / synthesis network (5) via a signal interface and a radio frequency interface to be divided into M paths of signals; according to information of an azimuth angle and a pitch angle of the phased array antenna provided by the transmitting signal processing terminal in real time, a beam controller (4) calculates and obtains beam pointing of the phased array antenna in real time through an FPGA; the beam pointing of the phased array antenna is converted into phase data needed by each array element under control of the beam controller (4); the data are transmitted to tilt-type TR assembly sub array modules in N channels respectively via a high and low-frequency interconnected multi-core high and low-frequency socket, and under control of the beam controller, M*N paths of signals are transmitted to an antenna array, and thus signal transmission is completed, and synchronous electric control scanning of beams transmitted by the phased array antenna is realized.

Description

technical field [0001] The invention belongs to the field of microwave and millimeter wave technology, and relates to a Ka-band tile-structure active phased array antenna based on a multifunctional integrated chip. Background technique [0002] The prior art active phased array antennas can be classified according to structural integration methods: a "brick" structure of vertically integrated horizontal assembly (LITA) and a tile structure of horizontally integrated vertically assembled (TILA). The "brick" structure phased array antenna adopts the placement direction of components perpendicular to the aperture of the phased array antenna array, and the TR component circuit adopts the longitudinal integration horizontal assembly (LITA) method; the tile structure phased array antenna places the components in parallel In terms of the aperture of the phased array antenna, the sub-array circuit adopts the method of horizontal integration vertical assembly (TILA). The "brick" str...
