  • Coupled loop array antenna
    Publication number: 20060132368
    Abstract: An antenna uses an at least substantially straight microstrip line as the feed for a linear array. A row of microstrip loops is located on a side of the feed line and at least substantially parallel to the feed line. Multiple iterations of this arrangement may be used to form a planar array antenna.

  • Horizontally polarized wide-angle radar object detection
    Patent number: 7009551
    Abstract: A radar includes fixed beam radar transmitter and receiver antennae that utilize mixed polarization to optimize the object detection field-of-view through an intervening plastic fascia. The transmitter antenna transmits radar energy with slant polarization, a first receiver antenna designed for short-range wide-angle object detection passes only horizontally polarized radar energy, and a second receiver antenna designed for long-range narrow-angle object detection passes only vertically polarized radar energy.
