1. A lightweight patch antenna, comprising:
a dielectric formed with a plurality of dielectric grooves;
an upper patch that is disposed on the dielectric and has an upper groove formed at a position overlapping the dielectric groove; and
a lower patch that is disposed under the dielectric and has a lower groove formed at a position overlapping the dielectric groove,
wherein the dielectric includes:
a first dielectric groove that is formed on a first side of the dielectric:
a second dielectric groove that is formed on a second side of the dielectric and disposed opposite to the first dielectric groove with a center point of the dielectric interposed therebetween; and
a third dielectric groove that is formed on a third side of the dielectric.
