    • A phase shifter assembly for use with a phased array antenna includes a plurality of phase shifter subarrays which are mounted on a ferri-magnetic substrate. There is a common power feed which is connected in series through a transmission line with each of the phase shifter subarrays. Additionally, a plurality of power combiners/splitters are connected into the transmission line to direct the proportionate power to each subarray. An alignment phase shifter is connected into the transmission line between adjacent subarrays and their associated power combiner/splitter. Separately from the transmission line, a driver is electronically connected in series with coils at each of the alignment phase shifters to alter the phase power which is fed into each of the subarray to align adjacent subarrays and produce a substantially continuous wave for the antenna. There is also a common driver which is electronically connected in series with each of the phase shifter subarrays to alter the phase of the power which is fed from the common power feed to the radiating elements of the antenna and thereby establish the direction of the radiated beam.

    • A phase shifter subarray which is useful with a phased array antenna, includes a plurality of phase shifter elements which have substantially equal finite lengths and which are mounted on a ferri-magnetic substrate. An electrical coil is disposed around selected portions of the substrate and a common feed is connected to each of the phase shifter elements to transmit energy through the phase shifter elements to the radiating elements of the antenna. A driver is connected to the coil, and the driver is activated to induce a magnetic flux in the selected portions of the substrate. This flux influences that part of each phase shifter element which is mounted in the selected portions of the substrate and, consequently, the phase of the wave energy which passes through the influenced part of each phase shifter element is shifted to predictably direct the beam radiated from the antenna. For one embodiment, each phase shifter element is bifurcated into first and second segments with the respective first segments being of different length. For this embodiment the flux influences only the first segments of the phase shifter elements. In another embodiment, the phase shifter elements are not bifurcated and, instead, the coil is tapered on the substrate to influence different lengths of each phase shifter element.
    • 与相控阵天线有用的移相器子阵列包括具有大致相等的有限长度并且安装在铁磁基片上的多个移相器元件。 电线圈设置在基板的选定部分周围,并且公共馈电连接到每个移相器元件以将能量通过移相器元件传输到天线的辐射元件。 驱动器连接到线圈,并且驱动器被激活以在衬底的选定部分中引起磁通量。 该通量影响安装在衬底的选定部分中的每个移相器元件的部分,并且因此通过每个移相器元件的受影响部分的波能量的相位被移动以可预测地指示从 天线。 对于一个实施例,每个移相器元件被分叉成第一和第二段,其中相应的第一段具有不同的长度。 对于该实施例,磁通仅影响移相器元件的第一段。 在另一个实施例中,移相器元件不是分叉的,而是线圈在衬底上渐缩以影响每个移相器元件的不同长度。

    • An electronically scanned array antenna useful for millimeter wavelength energy is disclosed. The antenna comprises a fully ferrite loaded square or round waveguide having radiating apertures spaced along part of its length. Rf energy is circularly polarized in the waveguide. The phase velocity of the wave is controlled by applying a longitudinal magnetic field to the ferrite to produce a controllable linear progressive phase of the energy radiated from the apertures to form a beam in the desired direction. The phase control is of a latching type using flux drive. The particular structure of the invention enables combining a plurality of branching array elements with a feed element to form an array capable of two dimension beam scanning.
