This work proposes a multiphysics design methodology for photonic‐based phased array antennas. It is based on the use of circuital and full wave electromagnetic solvers in conjunction with an optical numerical tool. To illustrate the proposed methodology, it is presented the design of a photonic beamformer for a phased array based on four patch antennas operating at 5.8 GHz. The array has been numerically evaluated using a 50‐km radio over fiber system, responsible to transmit the RF signal from the Central Office to the Remote Antenna Site. It has been used the following pieces of software: VPI Transmission Maker for optical domain simulations, Designer and HFSS from ANSYS for electrical domain simulations. The last two are easily integrated, as the same company had produced them. Conversely, it was necessary to create an efficiency interface for enabling the integration between VPI Transmission Maker and them. This interface enables the integration between the optical domain at hundreds of THz and the electrical domain at some GHz. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:838–843, 2014
