Abstract
A monopole antenna coupled to a metallic ground plane includes apertures used to steer a radio frequency (RF) beam of the monopole. The apertures may have a length, width, and distance from the monopole based on the wavelength of the RF signal used to drive the monopole antenna. The aperture may be coupled to one or more selective devices, such as PIN diodes, which may short portions of a metallic ground plane near the aperture. The shorted portions of the metallic ground plane provide for steering of the monopole radiation pattern. A circuit board metallic ground plane may include multiple apertures to direct different RF signal frequencies from a single monopole antenna. Multiple monopole antennas may be implemented over a metallic ground plane within a wireless device, each monopole antenna with corresponding apertures.
