This　paper　presents　a　novel　approach　for　independently　controlling　in-band　radiation　and　scattering　patterns　in　phased　arrays.　An　equivalent　circuit　model　is　developed　to　illustrate　the　underlying　operating　principle.　Based　on　this　principle,　radiation　beams　can　be　steered　through　appropriate　excitation　phase　distribution　without　affecting　the　scattering　patterns,　while　scattering　beams　are　controlled　by　designing　antenna　elements　with　tunable　surface　reflection　coefficients　but　identical　radiation　pattern.　To　validate　this　approach,　a　reconfigurable　antenna　array　incorporating　PIN　diodes　is　designed,　operating　over　the　2.6-3.4　GHz　frequency　range　with　a　±45°　scanning　angular　range.　Simulation　results　demonstrate　that　the　proposed　array　can　dynamically　reconfigure　its　scattering　beams,　directing　them　to　arbitrary　angles　within　±45°,　while　maintaining　good　radiation　performance.　©　2025　IEEE.
