  • Improvements relating to antenna arrays
    Patent number: 8253636
    Abstract: An improved antenna array (100) comprises a set of array elements (102 a-p) electromagnetically coupled to a transmission line. The transmission line comprises a live conductor (122) and a return conductor, and the live conductor (122) is terminated by a direct connection to the return conductor. An input signal fed to the live conductor (122) is radiated by the array elements (102 a-p) and the antenna array (100) is arranged such that any portion of the input signal reaching the termination is reflected at the termination so as to form a reflected signal that superimposes with the input signal to produce a predetermined farfield radiation pattern.
