Abstract: A method for making an antenna array includes forming a ground plane having spaced apart openings extending therethrough, and forming a first antenna board having a support section and spaced apart first legs extending outwardly from the support section. An antenna element is formed on each outwardly extending first leg. A second antenna board having a support section and at least one second leg extending outwardly from the support section is formed. An antenna element is formed on the at least one outwardly extending second leg. The outwardly extending first legs are inserted through a corresponding number of openings in the ground plane. Similarly, the at least one outwardly extending second leg is inserted through one of the openings in the ground plane. The first and second legs are inserted so that their respective support sections contact the ground plane.

Abstract: A communications device for separating source signals provided by M signal sources includes an antenna array comprising N correlated antenna elements for receiving at least N different summations of the M source signals, with N and M being greater than 1. A receiver is connected to the antenna array for receiving the at least N different summations of the M source signals. A blind signal separation processor is connected to the receiver for forming a mixing matrix comprising up to the at least N different summations of the M source signals, and for separating desired source signals from the mixing matrix. The mixing matrix has a rank equal to at least N.
