Abstract
A glazing unit (101) is provided configured for reception of radio frequency signals, the glazing unit (101) has an optical layer (143) including electrophoretic charged particles and being arranged between a first substrate (141) and a second substrate (142), electrodes (122, 123) on the substrates (141, 142) cooperate in the electrophoretic modulation of the charged particles' position causing modulation of light passing through the glazing unit (101). The glazing unit (101) has at least one antenna (121) for reception of a radio frequency signal. The antenna (121) may be arranged on a side of a substrate (141, 142) or on a side of a pane (111, 112), e.g., glass pane.
