摘要： A compact, low profile electronically scanned antenna module is provided. The antenna module includes a multi-layer antenna integrated printed wiring board (AiPWB) that includes a radiator layer on a front surface. The radiator layer includes a plurality of RF radiating elements. The antenna module additionally includes a plurality of radiator electronics modules orthogonally connected to a back surface of the AiPWB. The electronics modules are interconnected with radiating elements through the AiPWB and include a plurality of beam steering electronic elements mounted to a multi layer conformable substrate. The orthogonal connections allow the antenna module to have outer dimensions that are substantially equal to the dimensions of a perimeter of the AiPWB. Additionally, frequency and scanning angle requirements of the antenna module can be increased by merely increasing the length of the electronics modules in the orthogonal direction to allow for additional beam steering electronic elements needed to accommodate the increased frequency and scanning requirements.

摘要： A phased array antenna system having a corporate waveguide distribution network stripline printed circuit board. The stripline printed circuit board receives electromagnetic (EM) wave energy from a 1×4 waveguide distribution network input plate and distributes the EM wave energy to 524 radiating elements. The stripline circuit board enables extremely tight spacing of independent antenna radiating elements that would not be possible with a rectangular air filled waveguide. The antenna system enables operation at millimeter wave frequencies, and particularly at 44 GHz, and without requiring the use of a plurality of look-up tables for various phase and amplitude delays, that would otherwise be required with a rectangular, air-filled waveguide distribution structure. The antenna system can be used at millimeter wave frequencies, and in connection with the MILSTAR communications protocol, without the requirement of knowing, in advance, the next beam hopping frequency employed by the MILSTAR protocol.

摘要： A phased array antenna system formed from an antenna-integrated printed wiring board for performing the functions of a waveguide impedance matching layer, a honeycomb support structure, RF antenna probes, DC logic and RF distribution. The printed wiring board construction of the present invention significantly reduces the number of component parts required to form a phased array antenna assembly, as well as simplifying the manufacturing process of the antenna assembly. The antenna-integrated printed wiring board is formed from an inexpensive, photolithographic process to create a single part (or optionally a two part) structure for performing the above-listed functions.

The method of manufacturing an aperture plate for a phased array antenna includes sizing a plurality of waveguide transitions based upon certain operating requirements, determining a radiating lattice spacing and configuration based upon the operating requirements, determining a coupling lattice spacing and configuration based upon antenna electronics packaging, optimizing an aperture plate thickness to achieve the radiating lattice and the coupling lattice spacing and configuration, and forming the aperture plate.

摘要： A dual beam electronically scanned phased array antenna architecture is provided. The architecture includes a plurality of antenna modules substantially orthogonally connected to a signal distribution board. Each module includes a radiator board substantially orthogonally connected to a first end of a support mandrel. Each radiator board includes a plurality of radio frequency (RF) radiating elements. Each module additionally includes pair of chip carriers mounted to opposing sides of the respective mandrel and interconnected to the respective radiator board. Furthermore, each module includes signal transfer board formed to fit around a second end of the mandrel such that the signal transfer board is compressed between the mandrel the signal distribution board. Each module further includes a pair of signal distribution bridges mounted to the opposing sides of the mandrel. Each signal distribution bridge interconnects the respective chip carriers with the signal transfer board and distributes digital, DC and/or RF signals received from the signal transfer board to a plurality of beam scanning circuits included in the respective chip carrier. The orthogonal relationship between the RF radiating elements and the beam scanning circuits allow the modules to be connected to the signal distribution board in close proximity to each other such that the RF radiating elements of adjacent modules have a spacing of one-half wavelength or less. Therefore, a high frequency, dual beam electronically scanned phased array antenna can be constructed that is capable of having scanning angles of 60° or greater. Therefore, a high frequency, dual beam electronically scanned phased array antenna can be constructed that is capable of having very wide scanning angles of without introducing grating lobes.
