    • Antenna elements operable to radiate different patterns are provided. A particular apparatus includes a first antenna element having a plurality of radiating elements. Each of the radiating elements includes a first member having a first end and a second end. The first end is coupled to an antenna interface and the second end extends a length of the first member from the first end. Each of the radiating elements further includes a second member having a third end and a fourth end. The third end is electrically coupled to the first member at a point partway along the length of the first member. The fourth end extends away from the first member. When a first radiating element is radiating in the presence of a second radiating element, a null is generated in a radiation pattern of the first radiating element.

    • Various techniques are disclosed to suppress undesired signal components introduced by non-linear amplifiers of phased array antenna systems to accommodate bandwidths greater than one octave. For example, in accordance with one embodiment, a phased array antenna system includes first and second antenna elements adapted to provide first and second received signals in response to a radio signal. The second antenna element is rotated approximately 180 degrees in relation to the first antenna element. Amplifiers may amplify the received signals to provide amplified signals having a bandwidth greater than one octave. Undesired components of the amplified signals introduced by the amplifiers may be suppressed through appropriate phase shifts performed by associated phase shifters and/or power combiners. A power combiner may combine the first and second output signals to provide a combined signal, wherein the first and second undesired components are suppressed in the combined signal relative to the amplified signals.
    • 公开了各种技术来抑制由相控阵天线系统的非线性放大器引入的不需要的信号分量,以适应​​大于一个八度的带宽。 例如,根据一个实施例,相控阵天线系统包括适于响应于无线电信号提供第一和第二接收信号的第一和第二天线元件。 第二天线元件相对于第一天线元件旋转大约180度。 放大器可以放大接收的信号以提供具有大于一个八度的带宽的放大信号。 可以通过由相关联的移相器和/或功率组合器执行的适当的相移来抑制由放大器引入的放大信号的不期望的分量。 功率组合器可以组合第一和第二输出信号以提供组合信号,其中第一和第二不期望分量相对于放大信号被抑制在组合信号中。
