N2 - In this paper a leaky wave antenna is presented that utilizes a sinusoidally modulated reactance surface. Contrary to conventional designs the sinusoidal reactance variation is electronically controlled (rather than geometrically) using a frequency selective surface loaded with lumped capacitors. Using a very thorough analysis that utilizes the transverse resonance method it is demonstrated how to derive the necessary capacitance-to-reactance map. According to this map any desired surface reactance profile (that uniquely determines the radiation properties of the antenna) can be translated to a set of lumped capacitor loads. The proposed design methodology is numerically validated. Moreover, it is demonstrated that the resulting leaky wave antenna is highly efficient.
