  • Patent number: 11996618
    Abstract: Disclosed is a shaped horn in conjunction with a dielectric tube for enhanced aperture directivity that can achieve a near optimum efficiency. The shaped horn provides additional mode control to provide an improved off-axis cross-polarization response. The horn shape can be individually optimized for isolated horns or for horns in a feed array. The feed array environment can produce results that lead to a different optimized shape than the isolated horn. Lower off axis cross-polarization can result in improved efficiency and susceptibility to interference.

  • Patent number: 11978962
    Abstract: An antenna array that utilizes ground guard rings and metamaterial structures is disclosed. In certain embodiments, the antenna array is constructed from a plurality of antenna unit cells, wherein each antenna unit cell is identical. The antenna unit cell comprises a top surface, that contains a patch antenna and a ground guard ring. A reactive impedance surface (RIS) layer is disposed beneath the top surface and contains the metamaterial structures. The metamaterial structures are configured to present an inductance to the patch antennas, thereby allowing the patch antennas to be smaller than would otherwise be possible. In some embodiments, the metamaterial structures comprise hollow square frames. An antenna array constructed using this antenna unit cell has less coupling than conventional antenna arrays, which results in better performance. Furthermore, this new antenna array also requires less space than conventional antenna arrays.

  • Patent number: 11973500
    Abstract: A field programmable gate array (FPGA) utilizing resistive switching memory technology is described. The FPGA can comprise a switching block interconnect having a set of signal input lines and a set of signal output lines. Respective intersections of the signal input lines and signal output lines can have two resistive switching memory cells, a current differential latch, and a switching transistor (also referred to as a pass gate transistor) arranged in a circuit. Resistance states of the resistive switching memory cells can be programmed to control an output voltage state of the current differential latch. The output voltage state is latched into the current differential latch which can drive a gate of the switching transistor to activate or deactivate the switching transistor, which in turn activates or deactivates an intersection of the FPGA.
