Abstract
Provided is a dual frequency band radiator module. The radiator module includes a ground layer, a circular patch radiator disposed on the ground layer so as to be spaced apart from the ground layer by a predetermined length, a via-wall composed of a plurality of vertical probes extending from the ground layer to an area surrounding the circular patch radiator, and a port disposed between the ground layer and the circular patch radiator. The radiator module radiates a signal in a first frequency band based on the via-wall, and radiates a signal in a second frequency band different from the first frequency band based on the via-wall and the circular patch radiator.
