    • A multi-port radiator radiates electromagnetic signal in response to a beat frequency of a pair of optical signals. The radiator includes a multitude of optical paths each carrying an optical signal having first and second wavelengths. A multitude of frequency conversion elements convert the optical signals to electrical signals and deliver them to the radiator's multiple ports. The frequency of the electrical signals, and hence the frequency of the electromagnetic wave, is defined by the difference between the first and second wavelengths. The phases of the optical signals received by the frequency conversion elements are shifted with respect to one another. Optionally, the difference between the phases of the optical signals travelling through each pair of adjacent paths is 90. The first and second wavelengths are generated by a pair of optical sources and are optionally modulated before being combined and delivered to the optical paths.
