Abstract
In some embodiments, a phased array antenna includes a carrier; a first plurality of antenna elements carried by the carrier and configured to transmit and/or receive signals at a first value of a parameter, and a second plurality of antenna elements carried by the carrier and configured to transmit and/or receive signals at a second value of the parameter different from the first value of the parameter. The antenna elements of the first plurality of antenna elements and the second plurality of antenna elements are located within a common aperture of the phased array antenna.
Claims23
A phased array antenna, comprising:
- a carrier;
- a first plurality of antenna elements carried by the carrier, distributed in a first geometric pattern on the carrier, and configured to transmit and/or receive signals at a first value of a parameter;
- and
- a second plurality of antenna elements carried by the carrier, distributed in a second geometric pattern on the carrier, and configured to transmit and/or receive signals at a second value of the parameter different from the first value of the parameter, wherein antenna elements of the first plurality of antenna elements and the second plurality of antenna elements are located interspersed within a common aperture of the phased array antenna, and wherein the second geometric pattern is rotated with respect to the first geometric pattern.
