Abstract :
A novel Printed-Circuit-Board (PCB) solution to avoid common-mode resonances in connected arrays is proposed in this paper. It consists in a loop-shaped circuit that rejects common-mode current propagation over more than an octave bandwidth. The use of such common-mode rejection loop allows the design of linear and dual polarized array of connected dipoles, with cross-polarization levels lower than −17 dBs for elevation angles in the range ±45° and for all azimuths, over more than 30 % relative bandwidth. Full-wave simulations are presented to validate the design.
