Abstract
An antenna may include an antenna main reflector having a shape defining a focal area, and a dual-function antenna structure adjacent to the focal area defining a first antenna feed at a first frequency and an antenna subreflector at a second frequency. The dual-function antenna structure may include a concave substrate and an array of antenna elements carried by the concave substrate. The antenna may further include a second antenna feed adjacent to the antenna main reflector and operable at the second frequency to cooperate with the antenna subreflector and antenna main reflector.
Claims24
An antenna comprising:
- an antenna main reflector having a shape defining a focal area;
- a dual-function antenna structure adjacent to the focal area defining a first antenna feed at a first frequency and an antenna subreflector at a second frequency, the dual-function antenna structure comprising a concave substrate and an array of antenna elements carried thereby;
- and
- a second antenna feed adjacent to the antenna main reflector and operable at the second frequency to cooperate with the antenna subreflector and antenna main reflector.
A dual-function antenna structure to be positioned adjacent to a focal area of a main reflector, the main reflector having a second antenna feed associated therewith and operable at a second frequency, the dual-function antenna structure comprising:
- a concave substrate and an array of antenna elements carried thereby to define a first antenna feed at a first frequency and an antenna subreflector at the second frequency.
A method for making a dual-function antenna structure to be positioned adjacent to a focal area of a main reflector, the main reflector having a second antenna feed associated therewith and operable at a second frequency, the method comprising:
- forming an array of antenna elements on a concave substrate to define a first antenna feed at a first frequency and an antenna subreflector at the second frequency.
