  • Containment system and increased strength radome assembly
    Patent number: 10131445
    Abstract: A containment system for containing all or part of a radome and an external subassembly that is protected by the radome is disclosed. One embodiment of the containment system comprises a fabric material and an attachment system for attaching the fabric material to the radome and to the radome attachment ring. An increased strength radome for covering the external subassembly is also disclosed.
    Type: Grant

  • Reconfigurable resonant cavity with frequency-selective surfaces and shorting posts
    Patent number: 6448936
    Abstract: The present invention features a reconfigurable resonant cavity specifically for use with a slot radiator. A series of internal planes with frequency-selective materials disposed on their top surfaces, in conjunction with switchable shorting pins, is used to reconfigure the cavity's resonant frequency. PIN diodes, MEMS or other photonically or electrical activated switching devices may be used to selectively “activate” shorting pins. A single resonant cavity may be electrically reconfigured to operate at two, three, or even more different frequency bands.
