  • Notch-antenna array and method for making same
    Patent number: 9270027
    Abstract: The notch-antenna array includes at least one notch-antenna array element that includes a first notch-antenna radiator, and a second notch-antenna radiator disposed at an angle to said first notch-antenna radiator. The angle is preferably 90 degrees and the element is either a slant antenna or an orthogonal antenna. The first notch-antenna radiator and the second notch-antenna radiator are formed integrally with one another. Each of the first and second notch-antenna radiators has substantially planar opposing surfaces and a flared notch formed therein. Each of the first and second notch-antenna radiators have substantially planar opposing surfaces and a slot configured to receive a printed circuit board therein formed between the substantially planar opposing surfaces. The printed circuit board includes a substrate with one or more dielectric layers, and a feedline.

  • Low backscatter polymer antenna with graded conductivity
    Patent number: 7236139
    Abstract: Polymer antenna structures having low reflectivity and high efficiency are disclosed. Wire antennas can be configured from coaxial cable having center conductors and outer conductors made from conductive polymer. Fabrics can also be configured with conductive polymer antenna elements formed in or on the fabric. The conductive polymer antenna elements can be configured with a graded conductivity to facilitate capture (as opposed to reflection) of electromagnetic energy.
