Claim 0:
1. An antenna package comprising:
an antenna device comprising an antenna dielectric layer and an antenna unit disposed on the antenna dielectric layer; and
a flexible circuit board electrically connected to the antenna unit, wherein the flexible circuit board comprises:
a core layer having a first surface and a second surface that face each other;
a circuit wiring layer disposed on the first surface of the core layer, the circuit wiring layer comprising a signal wiring electrically connected to the antenna unit; and
a ground layer disposed on the second surface of the core layer to cover the circuit wiring layer in a planar view, the ground layer partially including a mesh structure,
wherein at least a portion of the mesh structure of the ground layer does not overlap the antenna dielectric layer in the planar view,
wherein the flexible circuit board has a bonding region bonded to the antenna device, a bending region and a body region, and the bending region is located between the bonding region and the body region,
wherein the ground layer includes a first solid portion disposed on a portion of the core layer in the bonding region, a second solid portion disposed on a portion of the core layer in the body region, and a bending portion disposed on a portion of the core layer in the bending region, and the bending portion includes the mesh structure,
wherein the antenna unit comprises a radiator, a transmission line extending from the radiator, a signal pad connected to one end portion of the transmission line and a ground pad disposed around the signal pad, and
the circuit wiring layer of the flexible circuit board further comprises a ground pattern disposed around one end portion of the signal wiring to overlap the ground pad in the planar view.
