Abstract

A multifunctional GNSS antenna includes a PCB and first and second dielectric plates arranged in a stacked manner. 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.
