The invention discloses a Ku band transmit-receive co-caliber multi-layer printed antenna which is characterized by including, from top to bottom, a radiation patch array and emission feed network layer provided with a radiation patch array and an emission feed network, a first dielectric layer, a metal formation, a second dielectric layer, a receiving feed network layer provided with a receiving feed network, a third dielectric layer, a meta ground connection support layer, a fourth dielectric layer, and an amplifying circuit layer provided with a receiving amplifying circuit and an emitting amplifying circuit; the emitting amplifying circuit is connected with the emission feed network, and the receiving amplifying circuit is connected with the receiving feed network. The Ku band transmit-receive co-caliber multi-layer printed antenna has the advantages of compact microstrip antenna structure, small volume, light weight, and the like, a low noise amplifier and power amplifier are integrated in the back side of the antenna, feeder loss between the low noise amplifier and power amplifier and the antenna is reduced, and the complete machine quality factor and efficiency can be improved. At the same time, the whole circuit structure adopts a multilayer printing technology, and is simple in process and low in cost.
