Abstract:
A method of providing a multiple mode antenna system, said method comprising:selecting first desired operating attributes, including a first angle and a first beam width, of a first antenna beam associated with a first mode of said multiple modes; selecting second desired operating attributes, including a second angle and a second beam width, of a second antenna beam associated with a second mode of said multiple modes; deploying a first number of antenna elements in a first predetermined configuration, wherein a first inter-element spacing of said first predetermined configuration is compressed as compared to a corresponding typical phased array configuration of said first number of antenna elements, and wherein said first inter-element spacing is selected at least in part to provide an antenna beam substantially meeting said first desired operating attributes using a first beam former consistent with said corresponding typical phased array configuration of said first number of antenna elements; and deploying a second number of antenna elements in a second predetermined configuration, wherein a second inter-element spacing of said second predetermined configuration is selected at least in part to provide an antenna beam substantially meeting said second desired operating attributes, and wherein ones of said second number of antenna elements are interspersed with ones of said first number of antenna elements.
