  • Patent number: 11158951
    Abstract: An example antenna system includes a connection member, a first pair of antipodal Vivaldi antennas, and a second pair of antipodal Vivaldi antennas. The first pair of antipodal Vivaldi antennas are coupled to the connection member, positioned co-planar with each other along a first plane, and inverted relative to each other. The first pair of antennas provide approximately 180 degrees of phase shift (frequency independent) for a first group of signals. The second pair of antipodal Vivaldi antennas are coupled to the connection member, positioned co-planar with each other along a second plane substantially orthogonal to the first plane, and inverted relative to each other. The second pair of antennas provide approximately 180 degrees of phase shift (frequency independent) for a second group of signals. The antenna system is configured to utilize the first and second pairs of antennas to transmit or receive signals with circular polarization.

  • Patent number: 6227144
    Abstract: A pet bowl with insect repellent including a bowl portion having a generally frustoconical configuration. The bowl portion has a narrow upper end and a wide upper end. The narrow upper end has a food holding recess extending downwardly therein. A cover portion is dimensioned for covering the bowl portion while leaving the food holding recess exposed. The cover portion has a generally frustoconical configuration. The cover portion has a narrow open upper end and wide open lower end. The narrow open upper end has an inwardly extending peripheral flange. The peripheral flange rests on the narrow upper end of the bowl portion. A circular poison band is removably positioned around the bowl portion.
