1. An antenna structure comprising:
an antenna unit comprising:
a radiator including a plurality of radiation portions, widths of which sequentially decrease:
a transmission line extending between the radiator and the signal pad;
a pair of a ground pattern disposed around the transmission line to be physically spaced apart from the radiator and the transmission line:
a signal pad; and
a ground pad spaced apart from the signal pad, and
a circuit board electrically connected to the antenna unit, the circuit board comprising a connection pad connected to the signal pad and a bonding pad connected to the ground pad, the bonding pad having an area smaller than an area of the ground pad.
