The PCB has a lower surface with a circuit network, which is covered by a metal shield cover. The first dielectric plate has an upper surface with a first metal layer and a lower surface attached to an upper surface of the PCB. A first feed probe penetrates the first metal layer and the first dielectric plate and is coupled with the circuit network. A third metal layer is embedded in an edge and a lateral surface of the first dielectric plate, and is coupled by a third feed probe with the circuit network while a first short-circuit probe shorts the third metal layer to ground. The second dielectric plate has an upper surface with a second metal layer coupled by a second feed probe with the circuit network. ## Claims ### Claim 1 A multifunctional GNSS antenna, comprising: a PCB, a first dielectric plate, and a second dielectric plate arranged in a stacked manner, the PCB having a lower surface provided with a circuit network, the circuit network being covered by a metal shield cover; the first dielectric plate having an upper surface provided with a first metal layer and a lower surface attached to an upper surface of the PCB, a first feed probe penetrating the first metal layer and the first dielectric plate to couple the first metal layer with the circuit network; a third metal layer being embedded in an edge and a lateral surface of the first dielectric plate, a third feed probe and a first short-circuit probe both penetrating the third metal layer and the first dielectric plate, and the third feed probe coupling the third metal layer with the circuit network while the first short-circuit probe shorts the third metal layer to the ground; and the second dielectric plate having an upper surface provided with a second metal layer, a second feed probe coupling the second metal layer with the circuit network after penetrating the second metal layer, the second dielectric plate, the first metal layer, and the first dielectric plate. ### Claim 2 (depends on 1) The multifunctional GNSS antenna according to claim 1, wherein the circuit network comprises a feed network, a filter circuit, and a low-noise amplifying circuit, the first feed probe and the second feed probe are coupled with the feed network, and the third feed probe is coupled with the filter circuit; the low-noise amplifying circuit is used to amplify an electrical signal received by the feed network. ### Claim 3 (depends on 2) The multifunctional GNSS antenna according to claim 2, wherein the lateral surface of the first dielectric plate is further provided with a fourth metal layer, and the fourth metal layer is coupled to the filter circuit by a fourth feed probe and is shorted to the ground by a second short-circuit probe. ### Claim 4 (depends on 3) The multifunctional GNSS antenna according to claim 3, wherein the lateral surface of the first dielectric plate is further provided with a fifth metal layer, and the fifth metal layer is coupled to the filter circuit by a fifth feed probe and is shorted to the ground by a third short-circuit probe. ### Claim 5 (depends on 2) The multifunctional GNSS antenna according to claim 2, further comprising a third dielectric plate having a lower surface attached to the upper surface of the second dielectric plate, and an upper surface provided with a sixth metal layer, a sixth feed probe penetrating the sixth metal layer, the third dielectric plate, the second metal layer, the second dielectric plate, the first metal layer, and the first dielectric plate successively, and the sixth metal layer being coupled to the feed network by the sixth feed probe and being shorted to the ground by a fourth short-circuit probe. ### Claim 6 (depends on 5) The multifunctional GNSS antenna according to claim 5, wherein two third metal layers and two third feed probes are provided, and the two third metal layers are arranged around the lateral surface of the first dielectric plate. ### Claim 7 (depends on 5) The multifunctional GNSS antenna according to claim 5, wherein three third metal layers and three third feed probes are provided, and the three third metal layers are arranged around the lateral surface of the first dielectric plate.
