Claim:
1. A wireless device for transmitting a radiation signal, comprising: a circuit board including a metallic ground plane and at least one substrate layer; a monopole antenna coupled to the circuit board and transmitting radio frequency (RF) signals, wherein the monopole antenna includes one or more loading structures to change a resonance of the monopole antenna; and one or more apertures in the metallic ground plane associated with the monopole antenna, wherein each of the one or more apertures has a corresponding shape and pattern, the corresponding shape and pattern being circular, elliptical, or regular polygonal, wherein at least one selectable radio frequency switch is positioned over each of the one or more apertures, and wherein the one or more apertures associated with the monopole antenna are selected based on their corresponding shape and pattern to beam steer specific RF signals transmitted from the monopole antenna via selection of associated RF switches.
