An optical network (46) for providing a wideband true time delay phased antenna array with simultaneous multiple beam capability is disclosed. The network (46) is provided for connection between plural beam ports (48-52M) and plural antenna elements (20-24N) for converting a received radio frequency (RF) planar wavefront to plural in-phase signals at one and only one beam port (48-52M). The converse is true for a transmitted wave. The network (46) includes a laser (30-34N) for each antenna element (20-24N) modulated by RF energy which is separated and delayed via optical dividers (35-39N) connected to optical combiners (40-44M) by optical fibers (46) of different lengths. Substantially all signals then arrive in-phase at one particular beam port (48-52M) for a receiver (56-60M) receiving a wave at one particular corresponding angle of inclination of the wavefront. In transmitted waves, appropriate radiations from the phased array differ by an amount to effect transmission in one particular direction corresponding to the beam port selected for energization by the transmitter.
