    • 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.
    • 耦合到金属接地平面的单极天线包括用于引导单极子的射频(RF)波束的孔。 孔可以具有基于用于驱动单极天线的RF信号的波长的单极子的长度,宽度和距离。 孔可以耦合到一个或多个选择性装置,例如PIN二极管,其可以在孔附近的金属接地平面的短部分。 金属接地平面的短路部分提供单极辐射图的转向。 电路板金属接地平面可以包括多个孔,以引导来自单个单极天线的不同RF信号频率。 多个单极天线可以在无线设备内的金属接地平面上实现,每个单极天线具有相应的孔。
