    • A horizontally polarized antenna array allows for the efficient distribution of RF energy into a communications environment through selectable antenna elements and redirectors that create a particular radiation pattern such as a substantially omnidirectional radiation pattern. In conjunction with a vertically polarized array, a particular high-gain wireless environment may be created such that one environment does not interfere with other nearby wireless environments and avoids interference created by those other environments. Lower gain patterns may also be created by using particular configurations of a horizontal and/or vertical antenna array. In a preferred embodiment, the antenna systems disclosed herein are utilized in a multiple-input, multiple-output (MIMO) wireless environment.
    • 水平极化的天线阵列允许通过可选择的天线元件和重定向器将RF能量有效地分配到通信环境中,所述天线元件和重定向器产生特定的辐射图案,例如基本上全向的辐射图案。 结合垂直极化阵列,可以创建特定的高增益无线环境,使得一个环境不会干扰其他附近的无线环境并避免由其他环境产生的干扰。 还可以通过使用水平和/或垂直天线阵列的特定配置来产生较低增益模式。 在优选实施例中,本文公开的天线系统用于多输入多输出(MIMO)无线环境中。

    • A circuit board for wireless communications includes communication circuitry for modulating and/or demodulating a radio frequency (RF) signal and an antenna apparatus for transmitting and receiving the RF signal, the antenna apparatus having selectable antenna elements located near one or more peripheries of the circuit board. A first antenna element produces a first directional radiation pattern; a second antenna element produces a second directional radiation pattern offset from the first radiation pattern. The antenna elements may include one or more reflectors configured to provide gain and broaden the frequency response of the antenna element. A switching network couples one or more of the selectable elements to the communication circuitry and provides impedance matching regardless of which or how many of the antenna elements are selected. Selecting different combinations of antenna elements results in a configurable radiation pattern; alternatively, selecting several elements may result in an omnidirectional radiation pattern.

    • A system and method for a wireless link to a remote receiver includes a communication device for generating RF and an antenna apparatus for transmitting the RF. The antenna apparatus comprises a plurality of substantially coplanar modified dipoles. Each modified dipole provides gain with respect to isotropic and a horizontally polarized directional radiation pattern. Further, each modified dipole has one or more loading structures configured to decrease the footprint (i.e., the physical dimension) of the modified dipole and minimize the size of the antenna apparatus. The modified dipoles may be electrically switched to result in various radiation patterns. With multiple of the plurality of modified dipoles active, the antenna apparatus may form an omnidirectional horizontally polarized radiation pattern. One or more directors may be included to concentrate the radiation pattern. The antenna apparatus may be conformally mounted to a housing containing the communication device and the antenna apparatus.
