Abstract:
1. A wide band antenna comprising: a first antenna unit disposed on a first surface of a dielectric substrate; a supply cable disposed on the first surface of the dielectric substrate, the supply cable being connected to a center of a short side of the first antenna unit, thereby supplying voltage to the first antenna unit; a first connector coupler disposed above or below an end portion of the supply cable on the first surface of the dielectric substrate, the first connector coupler being spaced apart from the supply cable; a second antenna unit disposed on a second surface of the dielectric substrate without overlapping the first antenna unit, the second antenna unit comprising a knob having a notch shape which faces the short side of the first antenna unit; a balun disposed on the second surface of the dielectric substrate, the balun facing the supply cable and being connected to the knob of the second antenna unit; a second connector coupler disposed on the second surface of the dielectric substrate, the second connector coupler being connected to a side of the balun that is not connected to the knob of the second antenna unit; and a stub disposed between the second antenna unit and the balun on the second surface of the dielectric substrate, the stub being connected to the second connector coupler.
