abstract

  • Leaky-wave antennas (LWAs) are considered a good option in applications where medium-to-high directivity levels are required. In this work, we present a new design methodology for dual-band LWAs (Fabry-Pérot type). The proposed methodology is based on the use of a single partially reflective surface (PRS) that fulfills the resonant condition at two different frequencies. Consequently, a dual-band single-layer antenna can be designed. The potential of this methodology is demonstrated through two different designs of antennas showing also how control of the directivity is also possible. A prototype is manufactured and measured to validate the presented methodology and theoretical results.
