Abstract [en]

This work is focused on developing a method for compensating the edge effects in a mid-sized antenna array. Initially the resonance shift for the E-plane with respect to element position and scan angle was studied in finite × infinite array of strongly coupled dipoles. We show that geometrical tuning on the outermost elements of the array results in a 40% bandwidth improvement at the edge elements for a 40± scan angle. This improvement is compared with the original edge element behavior and it is achieved with a VSWR < 3 for the worst element. These modifications were based into two observations. Primarily, it was shown that by electrically connecting the edge elements we obtain an improvement in the interelement coupling. By adding stripes to the arms of the edge dipoles we obtained an additional degree of freedom that was used to improve the impedance of the edge elements. This procedure resulted in almost uniform VSWR behavior for all elements up to the edge for the finite × infinite approach.
