Dual-band common-caliber brick type phased array antenna framework Technical Field The invention relates to the technical field of phased array antennas, in particular to a dual-band common-caliber brick type phased array antenna framework. Background The active phased array antenna has the advantages of rapid beam change, high gain, multi-target processing and the like, the application range of the active phased array antenna in civil fields such as communication, electronic detection, civil radar and the like is continuously enlarged, the application scene is also more and more, and the performance requirements on the integrated, miniaturized and multi-band work of the active phased array antenna are also continuously improved. In many practical application scenes, the installation and the use of the antenna have strict caliber size limitation, and how to realize dual-band co-caliber transceiving in a limited caliber space becomes an important direction for the research and the development of the active phased array antenna. In the prior art, most of traditional active phased array antennas can only realize the receiving and transmitting of single-band electromagnetic waves, if multi-band signal processing is required to be completed, a plurality of independent antennas are required to be configured, the volume and the weight of the whole equipment are increased, the integration difficulty of a system is also improved, and the application requirements of miniaturization and high integration are difficult to adapt. For a phased array antenna attempting to realize dual-band operation, in the conventional structural design, the radiating units and the signal processing components are mostly arranged in a plane, the space utilization rate is low, and under the condition of limited caliber, the reasonable layout of the two band radiating units and the corresponding components cannot be completed, so that the design target of dual-band co-caliber is difficult to realize. The active phased array antenna with the brick-type structure is an important direction of miniaturization research and development of the current phased array antenna, the TR component and the modulation circuit of the active phased array antenna are axially distributed, and are integrally arranged in a two-dimensional plane perpendicular to the antenna radiation array surface. When the radiation caliber of the antenna is limited, the structure can provide sufficient space for arrangement of large-scale devices by extending the axial space of the TR component, and meanwhile, the metal structural member of the brick type structure has good heat transfer and heat storage physical characteristics, can effectively transfer and dissipate heat generated by operation of the components, can meet the thermal control requirement of high-power electronic components, and provides heat dissipation guarantee for integrated arrangement of double-wave Duan Yuan devices. To realize dual-band co-aperture transceiving of the active phased array antenna with the brick structure, two key problems need to be solved, namely, one is to complete integrated layout of two different-band radiating units on an antenna radiating array surface, the other is to realize ordered arrangement of corresponding dual-wave Duan Yuan devices inside a TR (transmitter-receiver) component, and independent transmission and processing of dual-band signals are achieved through collaborative design of the array surface and the TR component. Based on the space and heat dissipation advantages of the brick structure, the design of the dual-band common-caliber brick type phased array antenna framework is developed, the technical problem of dual-band integration under a caliber limited scene can be effectively solved, and the application requirements of the civil field on multi-band and miniaturization of the phased array antenna are adapted, so that the design has important practical research and development and application values. Disclosure of Invention In order to solve the problems, the invention provides a dual-band common-caliber brick type phased array antenna framework, which realizes component arrangement of two wave bands by using the axial space dislocation layout of a brick type TR and realizes dual-band transceiving common caliber by an array surface dual-arm oscillator and a microstrip patch.
