Innovative Dual Band Reconfigurable Beam Forming Network for Conformal Arrays

An innovative dual band reconfigurable beam forming network for conformal arrays is introduced, based on a dual band power divider with independent power ratio in both WLAN frequency ranges. Each divider employs two dual band quadrature hybrids connected through two dual band phase shifters. Measured results show good performance in terms of return loss, isolation and power ratio accuracy, confirming the feasibility of the proposed architecture
