In this paper, far-field pattern of one-dimensional leaky-wave antenna (LWA) is directly synthesized by sinusoidally modulating surface currents of the antenna. Due to the characteristic of light cone in distinguishing surface waves and radiation waves, the numbers of the beams are selectable depending on the modulations. A one-dimensional substrate integrated waveguide (SIW) antenna producing two beams are designed and fabricated. Measurements agree very well with the simulations, indicating the validity of the presented synthesizing method as well as the practicalities of the presented SIW antenna
